摘要
本文提出一种测量孔边干涉螺接应力分布的新实验方法,用激光散斑干涉技术测量出由干涉螺接应力形成的孔周位移场分布,进而确定孔这应力分布,在保证测量精度同时,该方法体现出了简单,实用,有效等优点。
A new experimental method measuring interference stress distribution near holes was presented. The displacement fields around the holes forced by interference stress measured by laser speckles interferometry.The stress distribution was given. The method have many advantage: sensi tive,simple,effective.
