| 摘 要： | 本文应用反射式同轴全息干涉法与光弹性夹片技术结合,为测定三维模型内部应力的完全实验解提供了一种新方法。该方法能方便地获得单独的等和线干涉条纹图,光路简单且灵敏度高。文中给出了半无限体受集中力作用的实验解与理论解的结果比较,两者能很好地吻合。最后还给出了接触问题的应用实例,所得结果的静力校核误差小于5%。

| Abstract: | The holo-photoelastic sandwich method is proposed to obtain isopachic and isochromatie lines separately and the complete solution of stress in a 3-D model can be deter- mined experimentelly.The experimental results for the plane surface of a semi-infinite body un- der concentrated load agree satisfactorily with theoretical results.In addition,an application of this method to a contact problem is also given. |
