DYNAMIC ANALYSIS OF ELASTIC-PLASTIC SATURATED POROUS MEDIA BY THE BOUNDARY ELEMENT METHOD

Delfim Soares Junior, José Cláudio de Faria Telles, Webe João Mansur

Resumo


This paper presents a time-domain boundary element formulation for the dynamic analysis of saturated porous media. Integral equations for displacements, stresses and pore-pressures, based on non-transient fundamental solutions are considered. Elastoplastic models are also dealt with by the present methodology, extending the applicability of boundary elements to model complex pore-dynamic problems. At the end of the paper, a discussion concerning two numerical examples is presented, illustrating the potentialities of the new procedure.


Keywords: Boundary elements. Time-domain. Porous media. Elastoplasticity.
