Description
Summary:In this paper, a novel numerical method is presented to analyze the thermoelastic dynamic response of a long hollow cylinder made of functionally graded materials under radially symmetric dynamic mechanical and thermal loadings. That is utilizing finite difference method and Newmark method to solve the governing equation. The material of the functionally graded material hollow cylinder is assumed to change continuously along the thickness according to power-law distribution, except for a constant Poisson’s ratio, and the thermal boundary condition without internal heat source is considered. Comparisons between this paper’s results and the corresponding analytical results validate the solution proposed in this paper. Finally, the functionally graded material hollow cylinder under constant load and impulsive load are discussed in detail and many valuable thermoelastic dynamic characteristics are revealed.
