The experimented about the clay which it was high molecular matter (plastic materials), and a polycarbonate (PC) was used, and occurred on the crack tip, and it was analyzed. What is craze, there is a thing growing on a defect part of materials by a phenomenon peculiar of low crystallization nature high molecular matter such as a PC. The experiment method thought that technique of optics was effective than transparency of a PC as, and photoelasticity method and caustics method were used jointly by this study, and they experimented. CT specimen is used for reference by a JSME standard as specimen shape, a quantity of crack development, examination by crack opening displacement (COD) are done by a photoelasticity method, J value by measuring a diameter of a caustic image by caustics method was calculated.
