Argyris’ Natural Membrane Finite Element Revisited

 

Structural Membranes 2005

Stuttgart - Germany, 2-5 october 2005

 

Abstract

 

This paper presents the development of a useful membrane element based on Argyris’ natural formulation, making distinction between the constitutive and geometric parts of the element tangent stiffness. The mathematical development considers large displacements but linear elastic material behavior, yielding a very simple element, yet able to cope with the behavior of taut structures, like membranes. The formulation was implemented in the MATLAB numerical environment, and the paper compares numerical results to analytical solutions and experimental data, confirming a good performance for the proposed element.

Keywords: Natural Membrane Finite Element, Taut Structures, Tension Structures
