A Study on the Development of Stress Optic Law Considering Residual Stress in Photoelastic Experiment(II) -Application of Stress Optic Law Considering of Residual Sterss-

잔류응력을 고려한 광탄성실험의 광응력법칙 개발에 관한 연구 (2) -잔류응력을 고려한 광응력법칙의 응용-

Photoelastic experiment has been used to analyze stress of structure and stress in the vicinity of crack tip etc.. Model experiment such as photoelastic experiment has been restricted by problem of residual stress in the photoelastic model material. They are generated by molding, cutting and time effects etc.. They produce some errors in the results of photoelastic experiment data. In this paper, stress optic law considering residual stress already developed by authors was applied to the stress concentration problem and fracture mechanics. Although the specimen was bad with residual stress, we could obtain good results by using the stress optic law considering residual stress. It was found that the stress optic law of photoelastic experiment could be applied to the stress analysis of bimaterial.
