Abstract

This paper discusses crack propagation paths in a ceramic/metal functionally graded plate with two edge cracks under a transient temperature field. When the functionally graded plate is cooled from high temperature, curved or straight multiple cracks are observed on the ceramic surface. There are many types of crack propagation pattern. To investigate the mechanism of multi-crack initiation and crack propagation pattern, two crack paths are simulated using finite element method. The effect of the existence of a crack on propagation path of another crack are investigated and numerical results are shown in figures.
