摘要
研究了平面应力焦散线有效性的一些限制.当施加载荷、试件尺寸、光学装置的特征长度等物理量满足一定的条件时,得到的应力强度因子KI值是正确的,否则很可能是错误的.
This paper studies some limits of validity of plane stress caustics. whenthe applied loads,specimen dimensions and characteristic lengths of the opticalarrangement satisfy certain conditions the values of stress intensity factor K1 abtainedare accurate, otherwise are likely erroneous.
