| Research Abstract |
In the microstructure of ceramics the combination of the layered structure and the orientation is very effective for the functionality and mechanical properties, especially crystalline orientation is very important factor. In this study, we focused on the residual stress generated from the different coefficient of the thermal expansion depending on the each crystal axis and the orientation relationship between the crack growth direction and the cleavage direction for analyzing the crack propagation in single component ceramics. The residual stress can be introduced by the layer structure with alternative crystalline orientation, and it can be controlled by the thickness of each layer. The crack is deflected by the residual stress and the fracture mode depended on the crack-growth direction.
