The polymeric material is active now by various places in the society. In recent years, the polymeric material more than a metallic material is used, but there is not a lot of data of destruction under various environments. In the study, the CT specimen is produced with polycarbonate (PC), deterioration under the chemical environment is assumed, and it aims at the clarification of the craze phenomenon in the crack tip. To examine changing mechanical properties due to the medicine deterioration, the soaking examination that used the hydrochloric acid was done. And, the craze was caused in the crack tip by using the tension test. The photoelastic method and the method of caustics that was the technique of optics were used as a mode of analysis. It considered it as an evaluation method by using J-Integration value, the craze length and the crack length.
