摘要：

In this research, thick walled FGM spherical pressure vessels under internal pressure and temperature difference were studied. Material parameters were considered to vary as a power functions. In order to clarify the role of material parameters, several different materials with different parameters have been used. Different combinations of the internal pressure and temperature gradient loading were applied and their effects on the yield onset location, kinds of stresses and the role of temperature gradient, were studied. Linear kinematic hardening was supposed and the pressure vessel behavior under constant internal; pressure and cyclic temperature gradient, was obtained. (C) 2013 Elsevier Ltd. All rights reserved.
