0600352 电子散斑和全息光弹混合方法测量透明材料的应力强度因子[刊,中]／代祥俊／／山东理工大学学报(自然科学版)．-2005,19(2)．-49-53(G) 全息光弹性中等和线是获得断裂力学中应力强度因子的一种有效方法。但用传统的全息光弹性方法获取等和线需暗室,要经过显影定影及再现,而且不能直接数字化使其应用受到限制。提出一种将全息光弹性与相移电子散斑干涉有机结合的方法,不但克服传统全息光弹性的不足,而且使全息光弹性实现了数字化。
Journal of Shandong University of Technology (Natural Science Edition)]. Hybrid Speckle and Holo - Optical Hybrid Method for Measuring the Stress Intensity Factor of Transparent Materials. -2005,19 (2). -49-53 (G) Holographic photoelastic mid-sum lines are an effective way to obtain the stress intensity factor in fracture mechanics. However, the conventional holographic photoelastic method to obtain isosceles darkroom needs to be developed, fixed and reproduced, and its application can not be limited directly. A method of combining holographic photoelasticity with phase shift electronic speckle interference is proposed. It not only overcomes the shortcomings of traditional holographic photoelasticity, but also digitizes holographic photoelasticity.
