一种确定压剪全息干涉条纹级数的理论与实验研究
THEORETICAL AND EXPERIMENTAL STUDIES ON THE DETERMINATION OF ORDER VALUES OF THE HOLOGRAPH FRINGE IN THE COMPRESSIVE SHEAR
【摘要】 针对全息干涉条纹判读的难点 ,结合断裂力学知识、焦散线法和实时全息干涉 ,探讨了一种计算含有预制裂纹试样实时全息干涉条纹强度值的理论方法 .并进行实验验证 ,结果表明这种分析对于相关研究有一定的参考意义 .
【Abstract】 In order to overcome the difficulty in judging strain values of the holograph fringe, a method to calculate the strain value of the real time holograph fringe in a sample with prefabricated cracks in the compressive shear is developed by combining holograph, the caustics method and the fracture mechanics. A definite equation is established which is simple and easy to calculate, and is verified by tests.
