摘要：

The creep behaviour of a particle reinforced metal matrix composite is numerically modelled by use of the FE-method. In order to describe the influence of ceramic particles on the overall creep curve, idealised unit cell models, representing a periodic arrangement of particles are generated. The particles are assumed to react linear elastically. Particle cleavage is taken into account. For the matrix an additive viscosity hardening law coupled with an isotropic damage variable is used. Numerical studies depicting the influence of the particle's aspect ratio and the evolution of local damage on the global behaviour are presented.
