本文用激光散光法对有中心裂纹拉伸试件的Ⅰ型应力强度因子进行了测试,实验及分析表明:用激光散光法测应力强度因子比用透射式光弹法简便,而且有利于提高实验的精度,对于解决三维断裂力学问题有着良好的发展前景。
In this paper, I type stress intensity factor of central crack tensile specimen was tested by laser astigmatism method. The experiment and analysis showed that it is easier to measure stress intensity factor by laser astigmatism than that of transmission photoelastic method, The accuracy of solving the three-dimensional fracture mechanics has a good development prospects.
