摘要
通过对三种裂纹模式的概述,引出了铝合金断裂韧性的概念及断裂判据,重点评述了影响高强铝合金断裂韧性的内在与外在因素,以及断裂韧性与其它力学性能间的关系,最后提出了几个在今后的研究及应用中需要重点解决的问题。
The concept of fracture toughness and fracture criteria are presented based on a description of
three fracture models.Meanwhile,the intrinsic and extrinsic factors that have effect on fracture toughness of high strength aluminum alloys and the relationship between KIC and other mechanical properties are reiewed in detail.Finally,some problems on fracture toughness that we should pay more attention to in future research and application are discussed.
