Deep material networks for fiber suspensions with infinite material contrast
Benedikt Sterr, Sebastian Gajek, Andrew Hrymak +2
We extend the laminate based framework of direct Deep Material Networks (DMNs) to treat suspensions of rigid fibers in a non-Newtonian solvent. To do so, we derive two-phase homoge…
Second-order computational homogenization of flexoelectric composites
Xiaoying Zhuang, Bin Li, S. S. Nanthakumar +1
Flexoelectricity shows promising applications for self-powered devices with its increased power density. This paper presents a second-order computational homogenization strategy fo…
Modeling and Simulation of Chemo-Elasto-Plastically Coupled Battery Active Particles
Raphael Schoof, Johannes Niermann, Alexander Dyck +2
As an anode material for lithium-ion batteries, amorphous silicon offers a significantly higher energy density than the graphite anodes currently used. Alloying reactions of lithiu…
FFT-based investigation of the shear stress distribution in face-centered cubic polycrystals
Flavia Gehrig, Daniel Wicht, Maximilian Krause +1
The onset of nonlinear effects in metals, such as plasticity and damage, is strongly influenced by the heterogeneous stress distribution at the grain level. This work is devoted to…
An FE-DMN method for the multiscale analysis of thermomechanical composites
Sebastian Gajek, Matti Schneider, Thomas Böhlke
We extend the FE-DMN method to fully coupled thermomechanical two-scale simulations of composite materials. In particular, every Gauss point of the macroscopic finite element model…
Characterizing digital microstructures by the Minkowski-based quadratic normal tensor
Felix Ernesti, Matti Schneider, Steffen Winter +3
For material modeling of microstructured media, an accurate characterization of the underlying microstructure is indispensable. Mathematically speaking, the overall goal of microst…
Determining water mass flow control strategies for a turbocharged SI engine using a two-stage calculation method
Peter Hoelz, Thomas Boehlke, Thomas Kraemer
Reduction of heat and friction losses is a proven approach to increase the engine efficiency. Therefore, and due to a stabilized, robust combustion, a specific adjustment of compon…
Transient temperature calculation method for complex fluid-solid heat transfer problems with scattering boundary conditions
Peter Hoelz, Thomas Boehlke, Thomas Kraemer
A calculation method for engine temperatures is presented. Special focus is placed on the transient and scattering boundary conditions within the combustion chamber, including fire…
Modeling contrary size effects of tensile- and torsion-loaded oligocrystalline gold microwires
E. Bayerschen, A. Prahs, S. Wulfinghoff +4
When Chen et al. (2015, Acta Mater. 87, 78-85) investigated the deformation behavior of oligocrystalline gold microwires with varying diameters in both uniaxial tension and torsion…
Power-law Defect Energy in a Single-Crystal Gradient Plasticity Framework - A Computational Study
E. Bayerschen, T. Böhlke
A single-crystal gradient plasticity model is presented that includes a power-law type defect energy depending on the gradient of an equivalent plastic strain. Numerical regulariza…
Review on Slip Transmission Criteria in Experiments and Crystal Plasticity Models
E. Bayerschen, A. T. McBride, B. D. Reddy +1
A comprehensive overview is given of the literature on slip transmission criteria for grain boundaries in metals, with a focus on slip system and grain boundary orientation. Much o…
Equivalent Plastic Strain Gradient Plasticity with Grain Boundary Hardening and Comparison to Discrete Dislocation Dynamics
E. Bayerschen, M. Stricker, S. Wulfinghoff +2
The gradient crystal plasticity framework of Wulfinghoff et al. [53] incorporating an equivalent plastic strain and grain boundary yielding, is extended with additional grain bound…
