| 摘 要： | On the assumption that the yield criterion of orthotropic materials is isomorphic withHuber-Mises criterion of isotropic materials,we put forward a dimensionless stress yieldcriterion,and obtained the associated plastic flow law.Using experimental stress-straincurves in various simple stress states,generalized effective stress-strain formulae may bederived correspondingly in various forms. |
