摘要
本文用光弹法测定Ⅴ型切口尖端、应力强度因子。结果表明,等色线条纹数据应在y方向及其邻域测量。建议光弹图象放大50倍以上,并按文中的(4)式计算K_I。
In this paper, the determination of stress intensity factor of a V-notch by photoelastic method is presented. It is shown that the data of isoch-romatic fringe order should be measured in y direction and its neighbourhood. The photoelastic pictures are suggested to be magnified 50 times. The factors K1 are then calculated according to equation ( 4 ) .
