The internal stresses which may arise during sintering are modeled by calculating the behavior of coupled strings of circular particles. Strings consisting of large and small particles are connected in parallel and are allowed to sinter by surface and grain boundary diffusion. The strings consisting of the smaller particles experience tensile stresses, since their shrinkage is inhibited by the slower sintering of the larger particles. These internal stresses are followed as a function of time. The calculations provide a first‐order estimate of the internal stresses which may arise during the sintering of irregular arrays of particles.
