摘要

This paper is concerned with the application of two non-coaxial plasticity models in soil modelling and geotechnical analysis. These non-coaxial models have been developed based on early work of Spencer (1982), Harris (1993) and Rudnicki & Rice (1975) among others. Simple shear behavior and footing settlement problems are analysed by using the finite element program ABAQUS incorporating these two models in its material subroutines. Numerical results suggest that non-coaxial models tend to give a softer response.
