摘要
针对断裂韧度试样裂纹前缘不直度的分析,提出了凹型波浪形裂纹前缘心部无缺陷和带有缺陷(裂纹、夹杂及气孔等)试样的试验结果无效性判定方法。
This paper presents a criterion to identify the invalidity of test result for the fracture toughness specimen having 凹 ware form crack-front with or without defects (crack, impurity and hole) at its centre on the basis of the nonlinear analysis of the crack-front of fracture toughness specimen.
