基于有限元法的金属材料静强度破坏准则应用研究

Metal Material Static Strengh Failure Criteria Application Study Based on Finite Element Method

根据1种基于有限元法的金属材料静强度破坏准则,设计了2种净截面积相同的缺口试件,用弹塑性、大应变、大变形的非线性有限元方法对试件在静载荷作用下的破坏载荷进行了计算,并进行了试验验证。计算结果与试验结果相比误差很小,很好地验证了基于有限元法的金属材料静强度破坏准则。

A metal material static strength failure criteria based on FEM（finite element method） was used to design two kinds of notched specimens with same cross section areas.The specimens failure loads under the static loads was calculated and validated using elastoplastic,large strain and large displacement nonlinear FEM,the comparison showing little discrepancy between the calculation results and the testing results validated the metal material static strength failure criteria based on FEM successfully.
