网格法  实验应力分析方法的一种。网格法是在试件表面印制或刻划网格,则当试件受载而发生变形时,网格随之变形,通过测量网格因变形而引起的位移,以确定试件的位移场或应变场。它适用于测量5%以上的大应变,而用于测量较小的应变时,精度很低。通常用于测定金属的塑性变形(图 1),以及橡胶、塑料等弹性模量低的材料的变形(图 2)。此法于20世纪40年代开始应用,后来在较大程度上被云纹法所取代。  用此法测定试件的位移和应变分布时,须分别拍摄试件在受载前后的网格图(图3a、图3b),用负片测出网格交点在受载前后的坐标。根据各点受载前后的x、y坐标的差值,分别求出x方向和y方向的位移u和v的分布,再对坐标求导数,得出偏导数,然后按下列公式分别求出各点在x方向和y方向的线应变εx、εy和角应变γxy。                    参考书目   V.
