| Outline of Final Research Achievements |
Based on the changes in thermo-elastic properties of several ceramic materials from powder compact state to sintered body state, formulation was done on a generalized model for estimating stress generation during sintering of ceramics laminates, including several combinations of constitutive equations such as elastic, elasto-plastic, and visco-elastic materials. Form the collaborative researcher’s latest output, the priority of this project moved to homogeneity of powder compact because it was also strongly related to the cracking during sintering. The stochastic model was developed to express granule collapse probability in a powder compact, and homogeneity improvement was discussed with the model. Finally, accomplishment of this project was summarized.
