Daher gibt es starke Bestrebungen in diesem Bereich hin zu einer höheren Wirtschaftlichkeit, welche beispielsweise durch höheren Massedurchsatz bei gleichbleibender Maschinengröße erreicht werden kann, oder aber auch im Hinblick auf eine Kreislaufwirtschaft die Bestrebung hin zu einer materialschonenden Verarbeitung. Beide Bestrebungen erfordern spezielle Schneckenkonzepte. Hierunter fallenWave- Schnecken, welche in beiden Bereichen ein vorteilhaftes Prozessverhalten aufzeigen sollen. Die Auslegung von Wave-Schnecken erfordert jedoch ein stärkeres Verständnis über das geometrieabhängige Prozessverhalten in der Extrusion. \r\nIm Rahmen der Dissertation werden zwei Themengebiete angegangen. Das erste Thema ist die Herleitung einer Methode zur Charakterisierung des Abbauverhaltens von Thermoplasten sowie die Nutzung der Charakterisierung als Vorhersagemodell. Das zweite Thema behandelt die Auslegung von Wave-Schnecken basierend auf numerischen Simulationen samt Validierung anhand von sieben Energy-Transfer-Schnecken im Vergleich zu drei konventionellen Schnecken. Hierbei werden unter anderem der Materialabbau, die thermische und die stoffliche Homogenität betrachtet, um ein umfassendes Bild über das Prozessverhalten der Schnecken zu schaffen. Die vorgestellten Untersuchungen dienen schlussendlich zu einer Bestätigung des vorteilhaften Prozessverhaltens von Wave-Schnecken."},{"text":"The extrusion process is the dominant processing method for thermoplastics in terms of quantity. For this reason, there are strong efforts in this area towards greater economic efficiency, which can be achieved, for example, through higher mass throughput with the same machine size, or, with regard to a circular economy, towards material-preserving processing. Both endeavours require special screw concepts. These include wave screws, which should demonstrate advantageous process behaviour in both areas. However, the design of wave screws requires a better understanding of the geometry-dependent process behaviour in extrusion. \r\nTwo topics are addressed in the dissertation. The first topic is the derivation of a method to characterise the degradation behaviour of thermoplastics and the use of the characterisation as a predictive model. The second topic deals with the design of wave screws based on numerical simulations including validation using seven energy transfer screws in comparison to three conventional screws. Among other things, the material degradation, the thermal and the material homogeneity are considered in order to create a comprehensive picture of the process behaviour of the screws. The presented investigations ultimately serve to confirm the advantageous process behaviour of wave screws.","lang":"eng"}],"status":"public"},{"title":"Herstellung und Charakterisierung von Wood-Plastic-Composites (WPC) mit einer Matrix aus thermoplastischen Polyurethanen zur Erzeugung einer Holz-WPC-Verbundstruktur ","date_updated":"2024-02-21T18:09:39Z","author":[{"full_name":"Richters, Maximilian","last_name":"Richters","first_name":"Maximilian"}],"date_created":"2024-02-21T18:03:11Z","year":"2024","citation":{"bibtex":"@book{Richters_2024, title={Herstellung und Charakterisierung von Wood-Plastic-Composites (WPC) mit einer Matrix aus thermoplastischen Polyurethanen zur Erzeugung einer Holz-WPC-Verbundstruktur }, author={Richters, Maximilian}, year={2024} }","mla":"Richters, Maximilian. <i>Herstellung und Charakterisierung von Wood-Plastic-Composites (WPC) mit einer Matrix aus thermoplastischen Polyurethanen zur Erzeugung einer Holz-WPC-Verbundstruktur </i>. 2024.","short":"M.

Due to these advantageous properties, PC is often used in industry for example in medical devices, automotive headlamps, sporting equipment, electronics, and a variety of other products. PC is often subjected to uniaxial and biaxial loading conditions. Therefore, reliable material models have to take into account the various resulting experimental effects. For those reasons, we investigate PC specimens under uniaxial and biaxial loading by using different stretch rates and loading scenarios. In addition to that, we propose methods for optical measurement of local stretches to obtain the approximated local true stress. In future work, the displacement fields and the resulting reaction forces will be used for parameter identification of constitutive equations.</jats:p>","lang":"eng"}],"type":"journal_article","publication":"PAMM","doi":"10.1002/pamm.202300114","title":"Experimental investigations of uniaxial and biaxial cold stretching within PC‐films and bars using optical measurements","author":[{"first_name":"Ayoub","full_name":"Hamdoun, Ayoub","last_name":"Hamdoun"},{"first_name":"Rolf","full_name":"Mahnken, Rolf","id":"335","last_name":"Mahnken"}],"date_created":"2024-02-29T13:53:13Z","date_updated":"2024-02-29T13:58:38Z","publisher":"Wiley","citation":{"ama":"Hamdoun A, Mahnken R.

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."}],"status":"public","_id":"52233","user_id":"335","department":[{"_id":"154"},{"_id":"321"}],"keyword":["Applied Mathematics","Computational Mathematics","Computational Theory and Mathematics","Mechanical Engineering","Ocean Engineering","Computational Mechanics"],"language":[{"iso":"eng"}]},{"publication_status":"published","publication_identifier":{"issn":["2073-4352"]},"citation":{"ieee":"D.

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"}],"language":[{"iso":"eng"}],"keyword":["Inorganic Chemistry","Condensed Matter Physics","General Materials Science","General Chemical Engineering"]},{"_id":"53132","department":[{"_id":"9"},{"_id":"367"},{"_id":"321"}],"user_id":"44116","language":[{"iso":"eng"}],"type":"dissertation","status":"public","date_updated":"2024-04-02T12:43:05Z","date_created":"2024-04-02T12:40:06Z","author":[{"id":"38221","full_name":"Richters, Maximilian","last_name":"Richters","first_name":"Maximilian"}],"title":"Herstellung und Charakterisierung von Wood-Plastic-Composites (WPC) mit einer Matrix aus thermoplastischen Polyurethanen zur Erzeugung einer Holz-WPC-Verbundstruktur ","doi":"978-3-8440-9390-2","year":"2024","citation":{"short":"M.

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"}],"status":"public","_id":"53529","department":[{"_id":"624"},{"_id":"367"},{"_id":"321"},{"_id":"9"}],"user_id":"70729","language":[{"iso":"eng"}]},{"year":"2024","citation":{"ama":"Tölle L. <i>Ein Beitrag zur Steuerung der Faserstaubentwicklung faserverstärkter Kunststoffe beim mechanischen Recycling </i>.

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"}],"status":"public","type":"journal_article","publication":"PAMM","language":[{"iso":"eng"}],"_id":"56212","user_id":"85414","department":[{"_id":"9"},{"_id":"154"},{"_id":"321"}]}]
