Abstract
This paper examines the diffuse bifurcation mode of a two-layer specimen consisting of a non-coaxial Cam-clay model. The specimen undergoes a deformation by a prescribed velocity with no friction on the ends and a constant lateral hydrostatic pressure on the sides. We obtain several bifurcation loads and examine the effect of several material parameters on the bifurcation load. We finally investigate the sites where the slip planes first occur from the maximum shear strain point of view.
