Recently, varlous analyses applying to a non-coaxalCam-clay model, that is, the theory of shear bands formation based on finite strains/deformations, the estmation of slip surfaces based on bifurcation analysis, and the smulation of deformation behavior of clay using finite element analysis were carried out well.However, many uncertainties surround the influence of non-coaxial parameters on failure mechanism of the clay using non-coaxial Cam-clay model.
This paper shows that the influence of the non-coaxial parameter on the axial strain at forming shear bands and the inclination angle of formed shear bands is investigated by simulation of undrained shear under plane strain loading conditions using finite element analysis.
