Abstract

In this paper, FGMs are used as non-uniform materials in high temperature environments, especially in industries like aircraft, aerospace vehicles, nuclear plants and engineering structures. Different industries use them in thin and thick walled cylindrical pressure vessels. Based on the governing equations, differential equation of stresses is obtained in plastic state which can be widely used in the study of vessel and pipe behavior in elasto- plastic state. This research studies the temperature distribution and stress - strain relationships in the tube under internal pressure and temperature difference. Properties of these materials are considered as variable parameters function of radius. In this work, effects of these parameters have been investigated on yielding and the yield temperatures and stress changes under different loading in thickness of the tubes. Furthermore, it is shown that the structure of the tubes can be optimized by choosing appropriate parameters. In fact, by studying the four parameters, internal and external temperature, internal pressure and the yield stress together can be better analyzed on a functionally graded CYLINDRICAL TUBE, which has been shown at the end of the article.
