三维有限变形线性光弹性材料研究

Experimental Study of Three-dimensional Linear Photoelastic Material Subjected to Finite Deformation

制成了１５％应变量的三维有限变形线性光弹性材料，可供对橡胶类零件的应力分析之用；在该材料中，以尼龙６作内含体，可以制作初应力很小的三维有限变形复合光弹性模型。

The three -dimensional linear Photoelastic material subjected to finitedeformation for stress analysis of mechanical partS made of rubber mat6rinls has been developed.The lagrangian linear strain of this material can be as large as 15% in magnitude. The use of Nylon 6 as an insert in this material can be manufactured three-dimensional compositephotoelastic models in which the initial Stress is small.'
