| Abstract: | A finite element model has been developed to simulate nonlinear response of pile underaxial loading.The nonlinear stress-strain behaviors of soils are modeled via extend von Mises yield criterion.A parametric study is carried out to address the influence of various factors,such as yield criterion approximation,dilatancy,initial stress of self-weight,effect of interface element.on the prediction of pile behavior in elasto-plastic soils and key issues in the simulation are critically reviewed. |

| Keywords: | axial loaded pile extend Von Mises yield criterion soil-pile interaction |
