Abstract

A thermal shock problem of a functionally graded material plane (FGMP) containing a crack is considered. All the material properties of the FGMP are assumed to be dependent on the coordinates.The transient temperature fields are solved by combining the finite difference method (FDM) and the finite element method (FEM). Then the transient thermal stress intensity factors (TSIFs) are obtained using the interaction energy integral method. The transient characteristics of the TSIFs are investigated.
