“冻结”法是当前解决三维应力分析问题比较有效的方法,在工程中已获得了广泛的应用。 “冻结”法的实验程序是: 三维模型的应力“冻结”→沿需研究的截面切出薄片→将切片夹持于旋转台上,用偏光弹性仪或偏光显微镜,以平行光法或聚敛光法进行实验量测工作,获得必要的数据——等 “Freezing” method is a more effective method to solve the problem of 3D stress analysis. It has been widely used in engineering. The experimental procedures of the “freezing” method are: “Frozen” the stress of a three-dimensional model → Cut a slice along the section to be studied → Clamp the slice on a rotating table, and use a polarimeter or a polarizing microscope to measure the collimated light or convergent light. Methodology to carry out experimental measurements and obtain the necessary data - etc.
