[ 1 ] - Mechanical and Thermal Stresses In a Linear Plastic FGM Hollow Cylinder Due to Axisymmetric Loads

In this paper, an analytical solution for computing the linear plastic stresses and critical temperature and pressure in a FGM hollow cylinder under the internal pressure and temperature is developed. It has been assumed that the modulus of elasticity and thermal coefficient of expansion were varying through thickness of the FGM material according to a power law relationship. The Poisson's rati...
