Nonlinear Elasto-Plastic Analysis of Axisymmetric Spherical Shell by Chebyshev Spectral Collocation Method under the Pulsating Forces

Abstract:

This paper investigates nonlinear elasto-plastic analysis of the dynamic response of composite spherical shells base on the isotropic hardening and flow rule theorem. elasto-plastic strain-hardening is expressed at this stage and the plastic strain obtains to combine with elastic strain to present the elasto-plastic constitutive relation of composite spherical shells. Analytical solutions of the governing equations are based on the Chebyshev spectral collocation methods and then compare results with ABAQUS FEM. In numerical example, the effective of different external loads on the nonlinear elastic and nonlinear elasto-plastic of composite spherical shell are discussed in details.
