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…
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…
A Nonlinear Finite Element Heterogeneous Multiscale Method for the Homogenization of Hyperelastic Solids and a Novel Staggered Two-Scale Solution Algorithm
Bernhard Eidel, Andreas Fischer, Ajinkya Gote
In this paper we address three aspects of nonlinear computational homogenization of elastic solids by two-scale finite element methods. First, we present a nonlinear formulation of…
