9401970 Krishnaswamy This project is to supply funding for the development of a new photoelastic type shearing interferometer that is considered to be especially useful in bimaterial systems. Interfacial cracks that develop in bimaterial systems are inherently of the mixed-mode type which itself is somewhat ambiguous since it involves an arbitrary length scale. The proposed device is a combination of polariscope and a shearing interferometer which will be used to obtain all around maps of the crack tip fields for a wide range of material mismatch. ***

9401970 Krishnaswamy该项目旨在为开发一种新型光弹性剪切干涉仪提供资金，该干涉仪被认为在双材料系统中特别有用。 在双材料系统中发展的界面裂纹本质上是混合模式类型的，其本身有点模糊，因为它涉及任意长度尺度。 建议的装置是一个组合的偏光镜和剪切干涉仪，这将被用来获得周围的地图裂纹尖端场的材料失配范围很广。 ***
