英文摘要	In this paper, thermal response of an orthotropic functionally graded coating-substrate structure with a partially insulated interface crack under heat flux supply is considered. It is assumed that there exists thermal resistance to heat conduction through the crack region. The mixed boundary value problems are reduced to a system of singular integral equations and solved numerically. Higher order asymptotic terms for the singular integral kernels are considered to improve the accuracy and the convergence efficiency of the numerical integrals. Numerical results are presented to show the effects of the orthotropy parameters, thermo-elastic nonhomogeneity parameters, and dimensionless thermal resistance on the temperature distribution and the thermal stress intensity factors (SIFs).
