Project A01

Thermomechanical FE-FFT multiscale simulation of heterogeneous porous materials

The project A01 develops an efficient numerical multiscale model to describe the microscopic and macroscopic material behavior of hybrid porous (HyPo) materials using a Finite Element - Fast Fourier Transform approach. The influence of different microstructural morphologies, e.g. varying porosities, as well as hybrid material compositions on the macroscopic component properties will be simulated. Statistically similar representative volume elements  will be developed on a microscale, which can map the complex response behavior of the microstructure with simplified geometry. In addition, the project is developing suitable material models that reflect the specific thermomechanical properties of the microstructure. The mechanical and thermal behavior and their interaction are the focus of the modeling. The manufacturing process and the associated thermal effect on the material induce residual stresses, which are taken into account in the model.
Project A01 therefore cooperates with various projects from the fields of calculation and design, process design and production as well as characterization and properties.
