Simulation of Dual‐Phase Steel Using the Finite Cell Method and Voxel‐Based Microstructure Data

Abstract

For the modeling of micro-heterogeneous materials, the effective macroscopic response can be determined by means of computational homogenization. The complex morphology of the microstructure needs to be discretized efficiently for numerical simulations. To reduce the effort arising from the generation of a conforming finite element mesh the finite cell method is applied. In this contribution, we focus on the microstructure of dual-phase steel given by voxel-based data and present an approach that directly exploits such data for an efficient generation of an integration mesh.
