摘要
测量了激光照射后的受拉铝板试件的剩余强度,观察了不同激光照射时间下的裂纹扩展情况,并首次利用高温精细网格技术测量出试件上由激光破坏引起的裂纹尖端的残余变形场,为激光照射金属结构的实时动态变形测量提供了新的手段。
The experimental study on damage process of tensile aluminium plates under the laser radiation is presented in this paper.The superlattices for high temperature are successfully used to measure the residual deformation near the crack tip of a specimen which has got the laser radiation.
