Abstract

The orthotropic material which has been developed by authors using copper wires as fiber and epoxy resin as base material is necessary to know optical constants to determine a stress intensity factor by experiments. As a result, it was found that, by applying caustics theory, optical constants could quite easily be obtained in either case of experiments conducted with the specimen held in the air, immersed in liquid, or at the state of frozen stress.
