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>"}],"publication":"PAMM","type":"journal_article"},{"volume":299,"author":[{"full_name":"Hamdoun, Ayoub","id":"57708","last_name":"Hamdoun","first_name":"Ayoub"},{"first_name":"Rolf","id":"335","full_name":"Mahnken, Rolf","last_name":"Mahnken"}],"date_created":"2024-05-14T09:05:05Z","date_updated":"2024-09-26T11:25:29Z","publisher":"Elsevier BV","doi":"10.1016/j.polymer.2024.126981","title":"Uniaxial and biaxial experimental investigation of glassy polymers","publication_identifier":{"issn":["0032-3861"]},"quality_controlled":"1","publication_status":"published","intvolume":"       299","citation":{"short":"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>","lang":"eng"}],"publication":"Archive of Applied Mechanics","language":[{"iso":"eng"}],"page":"1221-1242","intvolume":"        94","citation":{"ama":"Hamdoun A, Mahnken R.

However, the utilization of their network capabilities is often challenging and error-prone because the whole network stack and communication patterns have to be implemented and managed on the FPGAs. Also, this approach conceptually involves a trade-off between the performance potential of improved communication and the impact of resource consumption for communication infrastructure, since the utilized resources on the FPGAs could otherwise be used for computations. In this work, we investigate this trade-off, firstly, by using synthetic benchmarks to evaluate the different configuration options of the communication framework ACCL and their impact on communication latency and throughput. Finally, we use our findings to implement a shallow water simulation whose scalability heavily depends on low-latency communication. With a suitable configuration of ACCL, good scaling behavior can be shown to all 48 FPGAs installed in the system. Overall, the results show that the availability of inter-FPGA communication frameworks as well as the configurability of framework and network stack are crucial to achieve the best application performance with low latency communication.</jats:p>","lang":"eng"}],"status":"public","type":"book_chapter","publication":"Lecture Notes in Computer Science","title":"Optimizing Communication for Latency Sensitive HPC Applications on up to 48 FPGAs Using ACCL","main_file_link":[{"open_access":"1"}],"doi":"10.1007/978-3-031-69766-1_9","date_updated":"2024-10-14T07:55:50Z","oa":"1","publisher":"Springer Nature Switzerland","author":[{"first_name":"Marius","last_name":"Meyer","full_name":"Meyer, Marius"},{"first_name":"Tobias","full_name":"Kenter, Tobias","last_name":"Kenter"},{"last_name":"Petrica","full_name":"Petrica, Lucian","first_name":"Lucian"},{"first_name":"Kenneth","last_name":"O’Brien","full_name":"O’Brien, Kenneth"},{"first_name":"Michaela","last_name":"Blott","full_name":"Blott, Michaela"},{"last_name":"Plessl","full_name":"Plessl, Christian","first_name":"Christian"}],"date_created":"2024-10-14T07:51:51Z","year":"2024","place":"Cham","citation":{"apa":"Meyer, M., Kenter, T., Petrica, L., O’Brien, K., Blott, M., &#38; Plessl, C.

The intensive computation and bandwidth demand for ERI evaluation presents a significant challenge for quantum-mechanics-based atomistic simulations with hybrid density functional theory: due to the tens of trillions of ERI computations in each time step, practical applications are usually limited to thousands of atoms. In this work, we propose SERI, a high-throughput streaming accelerator for ERI computation on HBM-based FPGAs. In contrast to prior buffer-based designs, SERI proposes a novel streaming architecture to address the on-chip buffer limitation and the floorplanning challenge, and leverages the high-bandwidth memory to overcome the bandwidth bottleneck in prior designs. Moreover, to meet the varying computation, bandwidth, and floorplanning requirements between the 55 canonical quartet classes in ERI calculation, we design an automation tool, together with an accurate performance model, to automatically customize the architecture and floorplanning strategy for each canonical quartet class to maximize their throughput. Our performance evaluation on the AMD/Xilinx Alveo U280 FPGA board shows that, SERI achieves an average speedup of 9.80 x over the previous best-performing FPGA design, a 3.21x speedup over a 64-core AMD EPYC 7713 CPU, and a 15.64x speedup over an Nvidia A40 GPU. It reaches a peak throughput of 23.8 GERIS ($10^9$ ERIs per second) on one Alveo U280 FPGA. SERI will be released soon at https://github.com/SFU-HiAccel/SERI.","lang":"eng"}],"status":"public","_id":"56609","project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"department":[{"_id":"27"},{"_id":"518"}],"user_id":"77439","language":[{"iso":"eng"}]},{"date_updated":"2024-10-31T07:37:26Z","author":[{"first_name":"David","last_name":"Scharwald","full_name":"Scharwald, David"}],"supervisor":[{"first_name":"Hans-Joachim","full_name":"Schmid, Hans-Joachim","id":"464","last_name":"Schmid","orcid":"000-0001-8590-1921"},{"full_name":"Jesinghausen, Steffen","id":"3959","orcid":"https://orcid.org/0000-0003-2611-5298","last_name":"Jesinghausen","first_name":"Steffen"},{"full_name":"Neitzel, Fabian","id":"72307","orcid":"0009-0004-8412-3645 ","last_name":"Neitzel","first_name":"Fabian"}],"date_created":"2024-10-31T07:37:16Z","title":"Intumeszierende Flammschutzmittel im Lasersinter-Verfahren: Optimierung des Brandschutzes, der mechanischen Eigenschaften und Analyse der Recyclingfähigkeit (Studienarbeit)","year":"2024","citation":{"ama":"Scharwald D. <i>Intumeszierende Flammschutzmittel Im Lasersinter-Verfahren: Optimierung Des Brandschutzes, Der Mechanischen Eigenschaften Und Analyse Der Recyclingfähigkeit (Studienarbeit)</i>.; 2024.","chicago":"Scharwald, David. <i>Intumeszierende Flammschutzmittel Im Lasersinter-Verfahren: Optimierung Des Brandschutzes, Der Mechanischen Eigenschaften Und Analyse Der Recyclingfähigkeit (Studienarbeit)</i>, 2024.","ieee":"D.

We outline and implement a largely analytic procedure forrigorous modal analysis of three-layer slabs with birefringent, anisotropic core. For Z-cut wave-guides, the slab eigenmode problem separates into uncoupled sets of scalar equations for TE andTM modes. Slabs in X-cut configuration support mostly mildly hybrid eigenmodes, with clear pre-dominant TE or TM polarization, and with effective indices that depend on the propagation directionof the modes, relative to the crystal axes. Strong hybridization can be observed for near degeneratemodes in singular configurations without vertical symmetry, or in symmetric slabs where two nearlydegenerate modes are of the same symmetry class. Dispersion curves for slab thickness and propa-gation angle are discussed, for slabs with oxide and air cover.

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"}],"type":"conference","publication":"IOM3.

These elongated grains can introduce anisotropy, negatively impacting the mechanical properties of the components. This study aimed to achieve controlled solidification with a fine-grained microstructure to enhance the mechanical performance of printed parts. Stainless steel 316L was used as the test material. High-intensity ultrasound was applied during the direct energy deposition (DED) process to inhibit the formation of columnar grains. The investigation emphasized the importance of amplitude changes of the ultrasound wave as the system’s geometry continuously evolves with the addition of multiple layers and assessed how these changes influence the grain size and distribution. Initial tests revealed significant amplitude fluctuations during layer deposition, highlighting the impact of layer deposition on process uniformity. The mechanical results demonstrated that the application of ultrasound effectively refined the grain structure, leading to a 15% increase in tensile strength compared to conventionally additively manufactured samples.</jats:p>","lang":"eng"}],"file":[{"relation":"main_file","success":1,"content_type":"application/pdf","access_level":"closed","file_name":"crystals-14-01001-v2 (4).pdf","file_id":"57470","file_size":5779744,"date_created":"2024-11-28T08:52:48Z","creator":"dlehnert","date_updated":"2024-11-28T08:52:48Z"}],"publication":"Crystals","ddc":["670"],"language":[{"iso":"eng"}]},{"language":[{"iso":"eng"}],"department":[{"_id":"149"},{"_id":"321"},{"_id":"9"}],"user_id":"76837","_id":"55638","project":[{"_id":"140","name":"TRR 285 – B01: TRR 285 - Subproject B01"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"status":"public","abstract":[{"lang":"eng","text":"<jats:p>Abstract.

Mixed crystals with arbitrary Nb–Ta ratios provide an additional degree of freedom to not only tune materials properties, such as the birefringence but also leverage the advantages of the singular compounds, for example, by combining the thermal stability of lithium tantalate with the larger nonlinear or piezoelectric constants of lithium niobate. Periodic poling allows to achieve phase-matching independent of waveguide geometry and is, therefore, one of the commonly used methods in integrated nonlinear optics. For mixed crystals, periodic poling has been challenging so far due to the lack of homogeneous, mono-domain crystals, which severely inhibit domain growth and nucleation. In this work, we investigate surface-near (&amp;lt;1μm depth) domain inversion on x-cut lithium niobate tantalate mixed crystals via electric field poling and lithographically structured electrodes. We find that naturally occurring head-to-head or tail-to-tail domain walls in the as-grown crystal inhibit domain inversion at a larger scale. However, periodic poling is possible if the gap size between the poling electrodes is of the same order of magnitude or smaller than the average size of naturally occurring domains. This work provides the basis for the nonlinear optical application of lithium niobate tantalate mixed crystals.</jats:p>"}],"status":"public"}]
