摘要：
In order to understand the thermal fracture properties of thermal barrier coating (IBC) systems, transient thermal stress intensity factors (TSIFs) are calculated by using the transient interaction energy integral method (IEIM) when a thermal shock load is applied. In this study, continuous and weak interfaces are studied. considering different distributions of the material properties and their derivatives in the interface. The effect of the interface bonding strength on TSIFs at crack tip of TBC systems with multiple interfaces is analysed. This method provides an avenue to simulate interfacial properties subjected to thermal shock loads.
