本文用力法编制了四边固支中心受集中力矩形薄板问题的计算机程序,可计算各点的挠度、斜率、剪力和弯矩;并用双曝光全息干涉法和夹层全息干涉法以及四孔散焦散斑干涉法分别对其挠度和斜率进行了测试,结果较为满意,说明这几种方法能很好地用于板的测试。 In this paper, a computer program was developed for the problem of concentrated thin rectangular plates with concentrated forces at the center of the four sides. The deflections, slopes, shear forces, and bending moments at each point can be calculated; and the double-exposure holographic interferometry, interlayer holographic interferometry, and four-hole defocusing are used. The speckle interferometry was used to test its deflection and slope, respectively, and the results were satisfactory. These results indicate that these methods can be used for plate testing.
