摘要
分析了焊后再热裂纹扩展量与断裂韧性的关系 ,建立了A710钢J积分断裂韧性随裂纹扩展量Δa变化的关联数模 ,从而为进一步研究材料断裂机理 。
The relationship between fracture toughness J and crack extension △a was analysized. The mathematical correlated model for predicting the J integral fracture toughness variation along with crack extension △a vs. J was determined for further studying the regime of material fracture toughness. Hence, for flawed PVP, it provides reliable criteria by means of the critical crack extension.
