Atomistic-Continuum Coupling by Homogenization
Aagashram Neelakandan, Karsten Albe, Bernhard Eidel
Classical atomistic simulations based on interatomic potentials resolve lattice instabilities, defect nucleation, and microstructure evolution with high fidelity, but their accessi…
Deep Convolutional Neural Networks Predict Elasticity Tensors and their Bounds in Homogenization
Bernhard Eidel
In the present work, 3D convolutional neural networks (CNNs) are trained to link random heterogeneous, two-phase materials of arbitrary phase fractions to their elastic macroscale…
Computational Homogenization of Concrete in the Cyber Size-Resolution-Discretization (SRD) Parameter Space
Ajinkya Gote, Andreas Fischer, Chuanzeng Zhang +1
Micro- and mesostructures of multiphase materials obtained from tomography and image acquisition are an ever more important database for simulation analyses. Huge data sets for rec…
From image data towards microstructure information -- accuracy analysis at the digital core of materials
Bernhard Eidel, Andreas Fischer, Ajinkya Gote
A cornerstone of computational solid mechanics in the context of digital transformation are databases for microstructures obtained from advanced tomography techniques. Uniform disc…
Exploring metamaterials' structures through the relaxed micromorphic model: switching an acoustic screen into an acoustic absorber
Gianluca Rizzi, Manuel Collet, Félix Demore +3
While the design of always new metamaterials with exotic static and dynamic properties is attracting deep attention in the last decades, little effort is made to explore their inte…
Error Analysis for Quadtree-Type Mesh-Coarsening Algorithms Adapted to Pixelized Heterogeneous Microstructures
Andreas Fischer, Bernhard Eidel
Pixel- and voxel-based representations of microstructures obtained from tomographic imaging methods is an established standard in computational materials science. The corresponding…
