was studied. Three yield criteria, including von Mises yield criterion, Mohr-Coulomb yield criterion and the unified yield criterion were used to describe the yield phenomena of the metallic glasses. Two classes of the experimental data were chosen to draw the yield loci using the unified yield criterion. It is shown that the unified yield criterion can be used to describe the yield behavior......
Equal perimeter yield criterion and its specific plastic work rate:Development, validation and applicationZHANG Shun-hu(章顺虎)1, ZHAO De-wen(赵德文)2, CHEN Xiao-dong(陈晓东)3(1. Shagang School of Iron..., Soochow University, Suzhou 215123, China)Abstract:In order to overcome the nonlinearity of Mises criterion, a new linear yield criterion with a dodecagon shape of the same perimeter as Mises criterion......
well with that by Spencer method, and it is more accurate than that from classic D-P criteria. Key words: yield criterion; non-associated flow rule; dilatancy angle; plastic potential function 1 Introduction A yield condition or yield criterion describes a material failure in structural plasticity. It defines the threshold state of a material between elastic and plastic or brittle failure......
