CALCULatING AND ANALYSIS FORCOD REDUCTION DFACTOR m OFSHALLOW CRACK

摘要

摘要: 本文提出了适用于工程中浅裂纹Ｊ积分和ＣＯＤ的关系式，根据实验和三维有限元计算的结果，对ＣＯＤ值减小因子ｍ值进行了分析，为浅裂纹断裂强度设计与断裂破坏分析提供一种思路．

Abstract: The relationship the between J integraland the crack opening displacement of the shallonecrack is discussed. According to results of experiment and 3-D FEM computation, COD reductionfactor m is analyzed. The method may be usedfor strength design and damage analysis of shallowcrack in engineering
