Two general formulations for second- and third-order ELDIRK methods have been obtained recently in Mahnken [21] with specific schemes,  e.g. for the embedded implicit Euler method, the embedded trapezoidal-rule and the embedded Ellsiepen method. In the first part of this paper, we investigate some general stability characteristics of ELDIRK methods, and it will be shown that the above specific RK schemes are not A-stable. Therefore, in the second part, the above-mentioned general formulations are used for further stability investigations, with the aim to construct new second- and third-order ELDIRK methods which simultaneously are A-stable. Two numerical examples are concerned with the curing for a thermosetting material and phase-field RVE modeling for crystallinity and orientation. The numerical results confirm the theoretical results on convergence order and stability."}],"title":"Construction of A-stable explicit last-stage diagonal implicit Runge–Kutta (ELDIRK) methods","author":[{"first_name":"Rolf","full_name":"Mahnken, Rolf","last_name":"Mahnken","id":"335"},{"last_name":"Westermann","id":"60816","first_name":"Hendrik","full_name":"Westermann, Hendrik","orcid":"0000-0002-5034-9708"}],"department":[{"_id":"154"},{"_id":"321"}],"citation":{"short":"R.

Unfortunately, studies investigating this alloy showed that additively produced samples exhibit anisotropic microstructures. This anisotropy compromises the mechanical properties and complicates the loading state in the implant. Moreover, the minimum requirements as specified per designated standards such as ISO 5832-11 are not met. The remedy to this problem is performing a conventional heat treatment. As this route requires energy, infrastructure, labor, and expertise, which in turn mean time and money, many of the additive manufacturing benefits are negated. Thus, the goal of this work was to achieve better isotropy by applying only adapted additive manufacturing process parameters, specifically focusing on the build orientations. In this work, samples orientated in 90°, 45°, and 0° directions relative to the building platform were manufactured and tested. These tests included mechanical (tensile and fatigue tests) as well as microstructural analyses (SEM and EBSD). Subsequently, the results of these tests such as fractography were correlated with the acquired mechanical properties. These showed that 90°-aligned samples performed best under fatigue load and that all requirements specified by the standard regarding monotonic load were met.</jats:p>","lang":"eng"}],"doi":"10.3390/cryst14020117","keyword":["Inorganic Chemistry","Condensed Matter Physics","General Materials Science","General Chemical Engineering"],"user_id":"35461","date_created":"2024-03-22T13:46:37Z","publisher":"MDPI AG","language":[{"iso":"eng"}],"publication_identifier":{"issn":["2073-4352"]},"year":"2024","status":"public","_id":"52738","date_updated":"2024-03-22T14:22:36Z","author":[{"first_name":"Dennis","full_name":"Milaege, Dennis","last_name":"Milaege","id":"35461"},{"last_name":"Eschemann","first_name":"Niklas","full_name":"Eschemann, Niklas"},{"full_name":"Hoyer, Kay-Peter","first_name":"Kay-Peter","id":"48411","last_name":"Hoyer"},{"first_name":"Mirko","full_name":"Schaper, Mirko","last_name":"Schaper","id":"43720"}],"intvolume":"        14","citation":{"short":"D.

A characteristic material property for polymers is the low thermal conductivity. However, for specific applications, such as additively manufactured injection molding tool inserts, increased thermal conductivity is advantageous. In this study, the influence of fillers of different types, shapes and sizes on the resulting thermal conductivity of compounds is investigated. The aim is to analyze the effects of the fillers, considering the FFF-typical strand structure. The first step is to characterize the fillers in terms of shape and size. Based on this, the resulting thermal conductivity of specimens manufactured in the FFF process for different build orientations is specifically examined and compared to injection molding. This ensures that the process- and material-related anisotropy of the specimens is considered in the analysis. For the evaluation, a methodology is developed to be applied in Laser Flash Analysis (LFA), which allows the results to be evaluated despite the characteristic FFF surface structure. For the final visualization of the influence of the particle size on the particle orientation, Scanning Electron Microscopy (SEM) images of the relevant polymer compounds are made. The investigations provide a data basis regarding the influence of the particle type, shape and size on the thermal conductivity as well as for the requirement-oriented selection of fillers for processing thermally conductive polymer compounds in the FFF process.","lang":"eng"}],"user_id":"70729","citation":{"ieee":"E.

The former is an adaptive mesh refinement on the macroscale, which allows to control the spatial discretization errors. The latter is an efficient combination of a numerically low cost nonuniform transformation field analysis (NTFA) and numerically high cost full‐field elasto‐plastic homogenization methods on the microscale. The present contribution deals with the application of the concept of downwind and upwind approximations to a goal‐oriented a posteriori error estimator based on duality techniques by means of reduced order homogenization schemes like NTFA, and with accuracy and numerical efficiency of the proposed goal‐oriented adaptive framework. NTFA consists of an offline phase and an online phase. During the offline phase, some relevant information of the micro system under consideration is precomputed allowing a reduced set of equations to be solved in the online phase. Thus, NTFA leads to a quite efficient homogenization method but less accurate compared to the full‐field homogenization method which is characterized with a high computational demand for accounting nonlinear microstructural mechanisms. Due to nonlinearities and time‐dependency of plasticity, the estimation of error transport and error generation are obtained with a backward‐in‐time dual method despite a high demand on memory capacity. In this contribution, the dual problem is solved with a forward‐in‐time dual method that allows estimating the full error during the resolution of the primal problem without the need for extra memory capacity. Several numerical examples illustrate the effectiveness of the proposed adaptive approach based on downwind and upwind approximations.</jats:p>","lang":"eng"}],"title":"Mesh‐ and model adaptivity for NTFA and full‐field elasto‐plastic homogenization based on downwind and upwind approximations","author":[{"first_name":"Arnold","full_name":"Tchomgue Simeu, Arnold","id":"83075","last_name":"Tchomgue Simeu"},{"first_name":"Rolf","full_name":"Mahnken, Rolf","last_name":"Mahnken"}],"department":[{"_id":"9"},{"_id":"154"},{"_id":"321"}],"citation":{"ieee":"A.

The numerical results obtained from standard viscoplastic material models exhibit mesh size dependency, requiring mathematical regularization. For this purpose, we present in this work a large deformation gradient theory for a viscoplastic isotropic material model published before. We extend our model to a micromorphic model by introducing a new micromorphic variable as an additional degree of freedom along with its first gradient. This variable represents a microequivalent plastic strain. The relation between the macroequivalent plastic strain and the micromorphic variable is accomplished by a micromorphic coupling modulus. This coupling forces proximity between the macro- and microvariables, leading to the targeted regularization effect. The micromorphic model is implemented as a three-dimensional initial boundary value problem in an in-house finite element tool. The analysis is performed for both uniaxial and biaxial specimens. The provided numerical examples show the ability of our model to regularize shear bands within the specimens and address the issue of localization.</jats:p>"}],"doi":"10.1007/s00419-024-02570-0","title":"A large deformation gradient theory for glassy polymers by means of micromorphic regularization","user_id":"57708"},{"doi":"10.1016/j.cma.2024.117277","project":[{"_id":"1218","name":"Hier20 - Zielorientierte Adaptivität für nichtlineare Homogenisierungen mittels hierarchischer Modelle","grant_number":"Geschäftszeichen: MA 1979/30-2"}],"title":"Downwind and upwind approximations for primal and dual problems of elasto-plasticity with Prandtl–Reuss type material laws","user_id":"85414","type":"journal_article","publication":"Computer Methods in Applied Mechanics and Engineering","quality_controlled":"1","article_number":"117277","volume":432,"intvolume":"       432","author":[{"last_name":"Mahnken","full_name":"Mahnken, Rolf","first_name":"Rolf"},{"last_name":"Tchomgue Simeu","id":"83075","full_name":"Tchomgue Simeu, Arnold","first_name":"Arnold"}],"department":[{"_id":"321"},{"_id":"154"},{"_id":"321"}],"publication_status":"published","citation":{"mla":"Mahnken, Rolf, and Arnold Tchomgue Simeu. “Downwind and Upwind Approximations for Primal and Dual Problems of Elasto-Plasticity with Prandtl–Reuss Type Material Laws.” <i>Computer Methods in Applied Mechanics and Engineering</i>, vol. 432, 117277, Elsevier BV, 2024, doi:<a href=\"https://doi.org/10.1016/j.cma.2024.117277\">10.1016/j.cma.2024.117277</a>.","bibtex":"@article{Mahnken_Tchomgue Simeu_2024, title={Downwind and upwind approximations for primal and dual problems of elasto-plasticity with Prandtl–Reuss type material laws}, volume={432}, DOI={<a href=\"https://doi.org/10.1016/j.cma.2024.117277\">10.1016/j.cma.2024.117277</a>}, number={117277}, journal={Computer Methods in Applied Mechanics and Engineering}, publisher={Elsevier BV}, author={Mahnken, Rolf and Tchomgue Simeu, Arnold}, year={2024} }","short":"R.

This new “TISTRAQ” process is comparable with press-hardening already known for steels and hot die quenching known for aluminium alloys. One of the main influencing factors for this process is the heat transfer coefficient (HTC). It is an important driver for adjustment of basic parameters, as selection of tool material or the forming speed but also plays an important role while elaborating temperature distribution in the numerical model. Therefore, a new and unique test rig was developed to determine the HTC and to perform tool-based heat treatment at specimen level under laboratory conditions. The test rig was used to investigate the influence of the titanium-tool-lubricant system on HTC and cooling rate. Further the effect of heat treatment in the test rig and tool-based quenching on microstructure and mechanical properties was studied.

This new “TISTRAQ” process is composed of two steps. In terms of process technology, the first step is comparable to a direct press-hardening process already well known for steels. In this step, the Ti-6Al-4V sheet material is resistively heated to a temperature below β-transus Tβ and, after a very short holding time, simultaneously formed and quenched by use of water cooled tools. Thereby, the β phase undergoes a martensitic transformation. The second step is a subsequent short-time annealing, which leads to a hardening of the material. In this work, a new test rig using resistive heating technique was used in order to produce\r\ndifferent solution treated and tool quenched (STQ) and subsequently annealed (STA) states. In this paper, the effects of heating rate, solution treatment temperature and holding time on microstructure and mechanical properties are addressed. For the characterisation, tensile testing and scanning electron microscopy were used. By the systematic variation of applied processing parameters, dominating effects on microstructure and mechanical properties were evaluated. For example, the solution treatment temperature was found to have a significant effect on microstructural features and characteristic strength and strain values. The obtained results reveal a high potential for future technical applications.","lang":"eng"}],"doi":"https://doi.org/10.7490/f1000research.1119929.1","_id":"49437","date_updated":"2025-05-19T11:46:28Z","date_created":"2023-12-04T11:08:49Z","publication":"IOM3.

Traditionally, joints are cylindrical and rotationally symmetric. In the present study, non-rotationally symmetric joints are used for joining steel and Glass mat-reinforced thermoplastic sheets (GMT). In addition, the study also analyzes the impact of non-rotational symmetric joint rotation on the load-bearing capacity. Single lap joint specimens were fabricated using the In-Mold assembly technique for joining steel sheets with GMT. Tensile shear tests were performed on different orientations of the joint geometry, and it was observed that changing the joint orientation influences the load-bearing capacity. The joints are constitutively modeled using beam elements and the influence of joint rotation on load distribution is examined through a static simulation study. </jats:p>","lang":"eng"}],"doi":"10.21741/9781644903131-183","project":[{"name":"TRR 285 – B01: TRR 285 - Subproject B01","_id":"140"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"author":[{"first_name":"Deekshith Reddy","full_name":"Devulapally, Deekshith Reddy","id":"76837","last_name":"Devulapally"},{"first_name":"Sven","full_name":"Martin, Sven","id":"38177","last_name":"Martin"},{"id":"553","last_name":"Tröster","first_name":"Thomas","full_name":"Tröster, Thomas"}],"title":"Non-rotationally symmetric joints – Mechanisms and load bearing capacity"},{"date_updated":"2024-12-02T13:46:39Z","_id":"57540","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0944-6524","1863-7353"]},"year":"2024","type":"journal_article","status":"public","date_created":"2024-12-02T13:43:15Z","publication":"Production Engineering","quality_controlled":"1","publisher":"Springer Science and Business Media LLC","department":[{"_id":"9"},{"_id":"158"},{"_id":"321"}],"citation":{"short":"S.

This can be overcome by using twin-roll casting to produce thin sheets. Further thermomechanical treatment, including hot or cold rolling, and heat treatment can adjust the mechanical properties of twin-roll cast Al-Li sheets. The whole manufacturing chain requires detailed knowledge of the precipitation and dissolution behavior during heating, soaking and cooling, to purposefully select any process parameters. This study shows the process chain of a twin-roll cast Al–Cu–Li alloy achieving a hardness of around 180 HV1 by adapting the heat treatment parameters for homogenisation, hot rolling and age hardening. Both hardness and microstructure evolution are visualised along the process chain.</jats:p>","lang":"eng"}],"doi":"10.1007/s11740-024-01322-x","title":"Process chain of a twin-roll cast aluminium-copper-lithium alloy","author":[{"last_name":"Mallow","first_name":"Sina","full_name":"Mallow, Sina"},{"full_name":"Broer, Jette","first_name":"Jette","last_name":"Broer"},{"last_name":"Milkereit","first_name":"Benjamin","full_name":"Milkereit, Benjamin"},{"id":"43822","last_name":"Grydin","full_name":"Grydin, Olexandr","first_name":"Olexandr"},{"first_name":"Kay-Peter","full_name":"Hoyer, Kay-Peter","id":"48411","last_name":"Hoyer"},{"orcid":"0000-0003-0741-3812","last_name":"Garthe","id":"11199","full_name":"Garthe, Kai-Uwe","first_name":"Kai-Uwe"},{"id":"35461","last_name":"Milaege","first_name":"Dennis","full_name":"Milaege, Dennis"},{"first_name":"Viktoriya","full_name":"Boyko, Viktoriya","last_name":"Boyko"},{"id":"43720","last_name":"Schaper","first_name":"Mirko","full_name":"Schaper, Mirko"},{"first_name":"Olaf","full_name":"Kessler, Olaf","last_name":"Kessler"}]},{"volume":15,"_id":"58309","issue":"1","date_updated":"2025-02-14T10:52:55Z","article_number":"160","publisher":"MDPI AG","date_created":"2025-01-21T13:48:05Z","quality_controlled":"1","publication":"Applied Sciences","status":"public","language":[{"iso":"eng"}],"type":"journal_article","year":"2024","publication_identifier":{"issn":["2076-3417"]},"publication_status":"published","user_id":"85414","citation":{"chicago":"Najafi Koopas, Rasoul, Shahed Rezaei, Natalie Rauter, Richard Ostwald, and Rolf Lammering. “Comparative Analysis of Phase-Field and Intrinsic Cohesive Zone Models for Fracture Simulations in Multiphase Materials with Interfaces: Investigation of the Influence of the Microstructure on the Fracture Properties.” <i>Applied Sciences</i> 15, no. 1 (2024). <a href=\"https://doi.org/10.3390/app15010160\">https://doi.org/10.3390/app15010160</a>.","short":"R.

Fracture methods considered encompass the intrinsic cohesive zone model (CZM) using zero-thickness cohesive interface elements (CIEs), the standard phase-field fracture (SPFM) approach, the cohesive phase-field fracture (CPFM) approach, and an innovative hybrid model. The hybrid approach combines the CPFM fracture method with the CZM, specifically applying the CZM within the interface zone. The finite element model studied is characterized by three specific phases: inclusions, matrix, and the interface zone. This case study serves as a potential template for meso- or micro-level simulations involving a variety of composite materials. The thorough assessment of these modeling techniques indicates that the CPFM approach stands out as the most effective computational model, provided that the thickness of the interface zone is not significantly smaller than that of the other phases. In materials like concrete, which contain interfaces within their microstructure, the interface thickness is notably small when compared to other phases. This leads to the hybrid model standing as the most authentic finite element model, utilizing CIEs within the interface to simulate interface debonding. A significant finding from this investigation is that within the CPFM method, for a specific interface thickness, convergence with the hybrid model can be observed. This suggests that the CPFM fracture method could serve as a unified fracture approach for multiphase materials when a specific interfacial thickness is used. In addition, this research provides valuable insights that can advance efforts to fine-tune material microstructures. An investigation of the influence of interfacial material properties, voids, and the spatial arrangement of inclusions shows a pronounced effect of these parameters on the fracture toughness of the material.</jats:p>","lang":"eng"}]}]
