Un Tratamiento de Material Tipo Goma, Mediante la Condensación de la Variable de Presión

Abstract

The paper present a finite element formulation to model hiper-elastic quasi-incompressible, rubber-like materials, taking into account large displacements and large elastic strains. The Ogden, Mooney-Rivlin and Neo-Hooke material models have
been implemented in a total Lagrangian formulation, decomposing the strain in its deviatory and volumetric parts and condensating the pressure variable at element level.
A brief review of the concepts of continuum mechanics is made, including large elastic strains. Validation examples are finally given.
