In this paper, we discuss the influence of the temperature dependence of material properties on transient thermal stresses in functionally gradient materials (FGMs). We consider a circular plate of FGM (ZrO2 and Ti-6 Al-4V) subjected to one rapid heating-cooling cycle. We analyze the transient thermal stresses by means of a finite element method. When the temperature dependence of material properties is considered, the maximum tensile stress is 10% less than the FGM with constant material properties at 300 K, and the maximum compressive stress is 30% less than that at 300 K. The maximum tensile stress is the lowest when the material properties of FGM are distributed linearly. The influence of the heating condition is also discussed.
