An Elasto-plastic Model for Liquefiable Sands Subjected to Torsional Shear Loadings

摘要：

　　This paper presents a modeling procedure for simulating the monotonic undrained torsional shear behavior of sands,including stress-strain relationship,and excess pore water pressure generation,while considering the void ratio and stress level dependence of stress-strain-dilatancy behavior of sand.A unique set of soil parameters is required by the model to satisfactorily predict the undrained behavior of loose and dense Toyoura sand over a wide range of initial void ratios and confining pressures,as proven by simulating experimental data produced by the authors and found in the literature.
