Abstract
This paper deals with a model to estimate an internal stress during sintering of ceramics laminates. This model was discussed previously, however, the authors have modified it into a more general form recently(especially cooling process during sintering). In this model, a symmetrical 3-layered laminate is considered, and one-dimensional elastic analysis is carried out. For heating, soaking at the sintering temperature, and cooling processes, the elastic stress in each constituent is given by using its sintering strain, thermal expansion strain, Young's modulus and volume fraction. Compared with the strength of each constituent sintered at the intermediate temperature, crack formation during sintering can be discussed.
