| 摘 要： | 提出一种对数微分法,有效地解决了光弹性实验中等倾线的提取问题,不仅可消除平面偏振光场中等差线对等倾线的影响,而且能高精度地提取任意复杂受力模型等倾线.最后给出了等倾线提取及精度分析的两个实例,实验证明;本方法具有广阔的应用前景.

| Abstract: | A new method which is called logarithm difference method,is proposed to extract iso clinice effectively from photoelastic experiments.It can remove the effect of isochromatics,and pro- vide a way to obtain isoclinic fringe patterns in complex photoelastio model automatically and accurate- ly.Two experiments were given to show the steps for extracting isoclinics and its accuracy was ara- lyzed. |
