The Analysis of Inflatable Antennas Using A Corotational Finite Element Approach
Abstract
The Jaumann stress strain approach has been used to evaluate a nonlinear structural response to a shell like geometry. The method employs a finite element solution incorporating the Jaumarin stress-strain relationships b d on large displacement and large rotation using a corotational technique. It is possible to evaluate the effects of irect and shear stresses within a laminated structure. Results show that the need for a correct thorough evaluation of the stresses of the shell is required as the shell thickness increases relative to the resulting geometry. In a predominately membrane resistant structure, the three types of theories, Eulerian, Jaumann and Lagrangian show close" comparison.
