3D MECHANICAL MODEL FOR DESCRIPTION OF LARGE ELASTIC DEFORMATIONS UNDER UNIAXIAL TENSION

Abstract

A 3D mechanical model for description of large deformations of non-linear elastic bodies is offered. The model describes various types of anisotropy, such as orthotropic, transversely isotropic, as well as isotropic bodies. The case of uniaxial tension is considered. Two characteristics of the nonlinear material similar to the linear Young's modulus and Poisson's ratio are investigated. The inner-model parameters effecting material specifications are analyzed.
