摘    要:对流行的R.Hill准则与新近提出的无量纲应力准则进行了三种材料薄壁圆管P-2比例加载的实验验证,实验结果表明:对于纯铝L2,与两个准则符合均良好;对于另外两种材料,实验点在两个准则的理论曲线之外,更靠近无量纲应力准则。

关 键 词:塑性  屈服准则  正交异性  实验

Abstract:A series of experiments with thin-wall pipe specimens of 3 sorts of materials (20# carbon steel, pure aluminium L2 and Mg alloy MB8) under P-p proportional loading was conducted for examination of the current R.Hill criterion and the recently propoced dimensionless stress criterion for orthotropic materials. The results of experiments show that the agreement of experimental data with the dimensionless stress criterion is better than that with R.Hill criterion.
Keywords:Plasticity  yield criterion  orthotropy
