摘要：

This paper deals with the problem of an edge crack in a semi-infinite nonhomogeneous plate under steady heat flux loading conditions. The objective of the study is to assess the effect of material nonhomogeneity on the thermal stress intensity factor. All material properties are supposed to be exponentially dependent on the distance from the boundary of the plate By using the Fourier transform, the problem is reduced to a singular integral equation that is solved numerically. The thermal stress intensity factors for various material constants are calculated. The results show that by selecting the material constants appropriately the stress intensity factor can be reduced.
