- Abstract
For the problem of a functionally graded thick-walled tube subjected to internal pressure, we have already presented the elasticity solution based on the Voigt method in Xin et al. (Int J Mech Sci 89:344-349, ). This paper discusses the elastic-plastic problem of the functionally graded thick-walled tube subjected to internal pressure and gives the solution in terms of volume fractions of the constituents. We assume that the tube consists of two linear work hardening elastic-plastic constituents and the volume fraction of one phase is a power function varied in the radical direction. The Lamé constants and yield stress of the constituents of the FGM tube are given rather than Young's modulus and yield stress with different unknown parameters of the whole material in the existing papers. As the internal pressure increases, the deformations of one phase and two phases from elastic to plastic are analyzed. The present method is valid for materials with different Poisson's ratios rather than constant Poisson's ratios usually used in the existing references to obtain the effective Young's modulus. More importantly, the influences of linear work hardening on plastic behavior are considered in this work.
