Abstract
The material Point Method (MPM) combines features of Finite Element and Discrete Particle methods. It is well suited to analyze geotechnical problems which involve large displacements and dynamic response. An explicit coupled hydro-mechanical formulation has been developed to analyze cases controlled by general loading and pore pressure generation and dissipation. The procedure has been successfully applied to reproduce the failure conditions of Aznalcóllar dam. The failure was explained by a c...
