Abstract: In this paper, isochromatic of interface crack tip in orthotropic bi-materials can be observed by photo-elastic coating. The mechanics parameters as well as other parameters are derived. The testing value of mixed stress intensity factors is obtained with photo-elastic equation by using curve fitting and regression analysis method. Compared with theoretical results, the theoretical formulas for interface crack tip in orthotropic bi-materials are verified. The distribution of stress field is observed.

Keywords: orthotropic bi-materials; interface cracks; stress field; stress intensity factor; photo-elastic coating; double dissimilar materials; curve fitting; regression analysis; interface crack tip.
