Determining precisely flaw sizes of structural materials is the basis of the application of fracture mechanics and damage tolerance design to the engineering.
准确测定结构材料中缺陷的尺寸是断裂力学和损伤容限设计在工程中应有的前提。

Stress raiser. A small flaw (internal or surface) or a structural discontinuity at which an applied tensile stress will be amplified and from which cracks may propagate.
一个小裂缝(内部或表面的)或者是结构不连续，在该处施加的拉伸应力将被放大，裂纹会扩展。
