Abstract
Numerical strategy of EFGM is presented for the analysis of saturated soil as an elasto-plastic material. First, a formulation is described for soil-water mixture using original Cam-clay model. Interpolating functions are used for the descrption of displacement instead of shape function of usual finite elements within a weak form. Numerical performance of the analyses of soil specimen under drained and undrained condition is then examined by comparing with finite element solutions. Stress path assures the solution with high accuracy in the case where the same arrangement of nodal points is adopted. Less accuracy is found in a different pattern of the nodal points scattering near/at the critical state. Further applicability to practical problems is also pointed out.
