Enrugamento de Membranas Anulares

Abstract

The present work studies the stability of homogeneous, isotropic, incompressible membranes, subjected to finite deformations. In those initially flata membranes, vertical and moment loads f and u, acts. The general equilibrium equations and boundary conditions were stablished throught the principle of stationary potential energy. The material was considered as being neo-Hookean. Throught small perturbations theory the stability was studied and checked with a simple experimental model.
