Abstract
Asymmetry of compression and sheer in porous media is considered. Sinc e the shear causes infinite stresses across the contacts, the models o f partial creep in shear are used to exclude the infinite stresses. Th e inelastic behavior in the shear nonlinear equations of motion corres ponding to the Korteweg-de Vries (KdV) equations in one-dimension lead to purely imaginary nonlinear term. This causes absorption and disper sion of P and especially S waves. (C) 1998 Elsevier Science Ltd. All r ights reserved.
