Summary
FEM-microanalyses for cyclic thermomechanical loads are performed on fibre-reinforced metallic matrix composites in order to study the damage history. First, material modelling is carried out in which, in addition to the elastic deformation, inelastic deformations (plasticity and creep) are taken into account. After the implementation of the model in the FEM, numerical shakedown simulations are performed in case studies.
