This paper deals with a model for estimating internal stress of each layer in ceramics laminates during sintering. The previous 3-layered model is extended into multi-layered (multi-phase) laminate model. One numerical example is shown for Porous Al_2O_3/Dense Al_2O_3/Porous Al_2O_3 laminate during heating, soaking, and cooling, and possible cracking is discussed. Finally, the effect of thermal expansion on the sintering strain is considered.
