| 摘 要： | 本文指出，在三维光弹性中也存在相似非耦联系统，文献［１］所提出的相似非耦联系统的模拟变分原理也适用于这种系统。并应用文献［１］中的模拟势能原理解决了一个重要理论课题即，三维光弹性体中有体力或惯性力作用时泊松比对冻结应力法精度的影响。

| Abstract: | This paper points out that there are also similarly non-coupled systems in three-dimesional photoelasticity. The simulated variational principles for similarly non-coupled systems proposed in the reference are also valid for these systems. and an important theoretical subject has been solved by the simulated potential energy princople proprosed in the reference. that is. the influence of Poisson ratio on the accuracy of stress . frozen method under body forces or inertia forces in three-dimensional photoelasticity. |
