Abstract: To evaluate soil-foundation interaction numerically, an isoparametric thin layer element is used within a 3-D, material nonlinear, general purpose geotechnical analysis system developed at Cornell University. Two quasi-linear models are proposed to describe the interface normal and shear behavior. Non-dilative behavior is assumed, and the Mohr-Coulomb criterion provides the normal stress-dependent shear behavior. Interface deformation modes simulated include stick, slip, debonding, and rebonding. Illustrative results demonstrate the usefulness of these models.
