Numerical analysis on dynamic response of saturated elasto-viscoplastic soft clay

In the framework of porous media model developed from mixtures theories, Solid skeleton of soft clay was viewed as elasto-viscoplastic material, and an elasto-viscoplastic model of saturated soft clay was established. According on the model of saturated soft clay, the penalty finite element formulation was attained by using Galerkin weighted residual method, and an iterative scheme was designed to solve the nonlinear finite element system equations of saturated elasto-viscoplastic soft clay. Taking advantage of the theory above mentioned, we workedout the finite element program and analyzed dynamic response of saturated elasto-viscoplastic soft clay. Some characteristics of dynamic response of saturated soft clay were presented.
