## Abstract In this paper the correspondence principle is used to reduce the equations of viscoelasticity to the equations of elasticity by means of a Laplace transform. The finite element technique is used to approximate these equations in Laplace transform space. The approximating equations are
Von Neumann stability analysis is performed for a Galerkin ΓΏnite element formulation of Biot's consolidation equations on two-dimensional bilinear elements. Two dimensionless groups-the Time Factor and Void Factor-are identiΓΏed and these quantities, along with the time-integration weighting, are use
