[1] The one-dimensional model of Rudnicki and Chen [1988] for a slip-weakening dilating fault is extended to include shear heating. Because inertia is not included, instability (a seismic event) corresponds to an unbounded slip rate. Shear heating tends to increase pore pressure and decrease the effective compressive stress and the resistance to slip and consequently tends to promote instabilit...

A finite element model has been developed to simulate nonlinear response of piles/drilled piers under axial loading. The nonlinear stress-strain behaviors of soils are modeled via Drucker-Prager and von Mises type plasticity. A parametric study is carried out to address the influence of various factors, such as soil friction approximation, dilatancy, effect of interface element and shear streng...

Most soil mechanics theories are limited to strain hardening and shrinkage under high compressive stresses, there some shortcomings in the selection of suction or degree saturation as water content state varies constitutive models unsaturated soil. Based on triaxial shear tests compacted (a silt plasticity) with different confining pressure (low-confining), a dilatancy model based mass is propo...
