Analysis of orthotropic behavior in convected coordinate frames

Abstract

The aim of this contribution is to present a theoretical and numerical model applicable to large strain analysis of orthotropic bodies. This three-dimensional constitutive law which uses the concept of convected coordinate frame is devoted to materials presenting elastic orthotropic behaviors in the large deformation field such as the elastomer-fabric composite materials. The proposed model is implemented in a finite element code and numerical examples are given to demonstrate the effectiveness of the model and the numerical algorithms. Finally, the model is compared to experimental results obtained from a bulge test.
