用试件P—δ曲线建立失效评定曲线的近似方法

Approximation of Establishing Failure Assessment Curves with P-δBehaviour of Specimens

提出一种利用带裂纹试件的载荷－载荷线位移（Ｐ－δ）曲线建立失效评定曲线的近似方法，与有限元方法比较，二者有很好的一致性．实例分析表明，此方法建立的失效评定曲线偏于保守．

An approximation of establishing failure assessment curves has heen proposed bymeans of the load-load line displacement(P-δ)behaviour of specimens.Comparing with finite element method,resultobtained from the approximation is consistent.Example analysis showed that the failure assessment curves establishing with the approximation is tend tobe conservative.
