平面环形域上径向裂纹应力强度因子K_I的光弹性求解

A Fhotoelastic Solution of Stress Intensity Factor K_1 for Radial Crack in Plane Annular Region

本文用光弹性方法首次给出了有限圆板及环形域径向裂纹K_1的一些实验结果.实验结果和理论值的对比相符合,本文给出的实验求解方法对此类问题有普遍意义,对工程实际问题有实用性.

Some experimental results of the stress intensity factor K_1 are obtained for the firsttime by the photoelastic method for a radial crack in a finite circular plate or in the planeannular region. The experimental results meet with the theoretical values. The methodfor experimental solutions given in this paper is of universal significance and can be veryUseful for solving practical engineering problems.
