Dynamic Large Deformation Analysis of Functionally Graded Shallow Spherical Shells

Abstract

This paper is concerned with the numerical analysis of dynamic thermal stress and dynamic buckling of elastic shallow spherical shells made of functionally graded materials. The calculations for evaluating displacements and stresses are based on the conventional theory of elasticity that geometric nonlinearity is taken into account. A modified 8-noded quardrilateral finite element is utilized for the analysis.
