| Abstract: | Summary Thermal cracking in a ceramic/metal functionally graded plate is discussed. When a functionally graded plate is cooled from
high temperature, curved or straight crack paths are experimentally observed on the ceramic surface. One of the reasons that
make the crack paths to differ are the thermal or mechanical conditions. In order to clarify the influence of these conditions
on the crack path, the crack propagation is simulated using finite element method.
