Abstract Bifurcation and post-bifurcation behaviors of thick-walled elastic-plastic circular tubes subjected to uniform shrinking are analyzed numerically under plane strain condition. Bifurcation analysis to determine the condition for onset of bifurcation away from the axisymmetric deformation is carried out within the framework for such analyses, due to Hill. The influence of the material properties and the dimensions of the tubes, upon the bifurcation behavior is clarified. In order to simulate the post-bifurcation behaviors of the tubes after the onset of surface type bifurcation, a finite element analysis of uniform compression of a block is performed under the plane strain condition. The localization of deformation into a narrow band induced by the nonlinear growth of surface undulation is clarified.
