The polycarbonate of the polymeric material was assumed to be test material in this research, and a dynamic three-point bending was done under the low temperature environment. The low temperature environment used and reproduced the liquid nitrogen. The crack of notch was inserted in the test specimen, and it experimented. The experiment used the simple high speed photography and the caustics method. The analytical result is used. It took a picture of the caustics image and the dynamic stress intensity factor was calculated. And this experiment was evaluated from the requested dynamic stress intensity factor. As a result, the dynamic fracture behavior of the polycarbonate with the low temperature environment effect in the dynamic load was examined. As a result, some tendencies were obtained in this experiment.
