Response of Saturated Porous Nonlinear Materials to Dynamic Loadings

Abstract

Past theoretical treatments of two phase media are reviewed and incorporated into the two phase dynamic finite element code TPDAP. A study of the response of two phase porous elastic media to dynamic uniaxial loadings is conducted and the influence of loading shape, material properties, and numerical techniques and parameters are evaluated. A series of calculations simulating uniaxial loadings of saturated soils having hysteretic skeletons is conducted. Zones of liquefaction occurring in these calculations are identified and the mechanics of liquefaction and influence of parametric variations on liquefaction are investigated and described.
