This article presents some modifications of the solid state sintering model summarised in Riedel and Blug (2001) and shows its application for the simulation of distortions due to co-sintering of composite structures. The densification due to rearrangement in the early stage of sintering is taken into account by introducing an extra term in the viscosity. Detailed analyses of a layered thin structure are conducted with the finite element method and the results are compared to various analytical approximations for the case of a thin layer on a thick substrate. Two more examples show the applicability of the model to cases of practical interest.
