At present, with the promotion of scaling-up, performance intensification and speeding-up of machines and their structual components, heat intensity problems have become an important issue in engineering. And the study of wear and fractures resulting from heat stress are of great importance in the safety design of such equipment. The stress intensity factor has been used as a measure of the near-stress-field intensity around the crack tip in various fracture problems. It can be determined by using simple equipment and following an easy procedure by the method of caustics, though it can also be obtained experimentally by means of photoelastics. In this study, the relationship between the stress intensity factor and the time or the depth of the crack in the blocks (made of polymeric materials such as epoxy and acrylic resin) with their crack side subjected to heat loading was investigated.
