Abstract

Abstract

With the porous media model based on mixture theory,a finite element formulation for dynamic transient analysis of fluid-saturated two-phase porous media is presented.Time integration of the equation,deduced with penalty method,can be performed by using implicit or explicit method. One-dimensional wave propagation in column under step loading and impulsive loading are analyzed with the developed finite element program.The obtained curves of displacements,velocities,effective stresses and pore pressures against time demonstrate the existence of wave propagation phenomena,which coincide with the theoretical results.
