A numerical model for the simulation of the complex material behaviour of particulate cellular solids on the mesolevel of single foam pellets is presented. During the deformation process, extremely large local deformations can occur, that are resolved using a displacement‐based arbitrary Lagrangian‐Eulerian approach. A special treatment of the thermomechanical problem is able to account for the highly non‐linear thermomechanical material behaviour of the foam material.
