FINITE ELEMENT ANALYSIS WITH MATERIAL NONLINEARITIES: THEORY AND PRACTICE,

Abstract

A survey of finite element analysis with inelastic material behavior is presented. The constitutive relations for creep and elastic-plastic behavior are first reviewed. These are used to form generalized stress-strain relations for plates and shells. The master stiffness equations are then developed for use with either the method of initial strains or the tangent modulus method. Considerations are given to factors affecting the choice of either method. Case studies are used to illustrate the state-of-the-art in inelastic analysis. (Author)
