A model for prediction of damage development during sintering is put forward. The model is based on the homogenization of sintering behaviour of a single neck between particles over all necks in material. The damage is treated as broken necks. Numerical analysis is based on a finite element implementation of a macroscopic extremum statement of the problem. The model predicts the volume distribution and evolution of damage in powder compacts under constrained sintering. Despite the generally: justified consolidating role of sintering some examples of the existence of stable damage zones in materials are considered. (C) 2001 Elsevier Science Ltd. All rights reserved.
