%X By comparing with the results given by analytic method,the advantages of employing numerical method to analyse material bifurcations are displayed in this paper.Under the loading conditions of uniaxial and slightly biaxial tension,the characteristics of material bifurcations(plane shear banding and surface wrinkling)are demonstrated. Uniaxial tension testings justify that the critical stresses given by calculations are reasonably fair.
