Abstract

Abstract: Elastic bodies having different modules in tension and compression exhibit nonlinear behaviors. The constitutive equations of an elastic body with different modules depend on the material itself, and also on the stress and strain state of each point in the body. Recent achievements of research on the constitutive equations are presented. Also discussed are the improvements in the finite element method (FEM) employed to solve different module problems. Analytical methods of the elastic body with different modules are introduced. Problems to be solved next are outlined.

Key words: analytical method, constitutive equation, different module, elasticity theory, finite element method (FEM)
