Babak Foroughi, H. Peter Degischer and Andreas Kottar Characterization and Simulation of Tensile Deformation of Non-Uniform Cellular Aluminium Until Damage Advanced Engineering Materials 15
Foamed metals exhibit a non-uniform cellular structure, which is characterized by computed X-ray tomography of low resolution applicable to large components. A material model is deduced transforming the cellular structure into 3D mass density distributions, which are converted into finite elements of different densities. Scaling laws are applied to simulate the deformation of samples submitted to tensile tests. The simulated elasto-plastic stress–strain curves agree with the experimental ones as well as the positions of predicted cracks with their observed occurrence.
