Abstract
To analyze the stress concentration factor, stress distributions and fracture mechanics under forces in composite or concrete structures by photoelastic experiments, it is necessary to develop photoelastic-model materials. An orthotropic photoelastic-model material for transparent-type photoelastic devices was developed in this study ; it is called a copper fiber epoxy composite (abbreviated as C.F.E.C.). It was found that the C.F.E.C. developed in this study satisfies the property requirements of a photoelastic-model material, C.F.E.C. has the complete properties of a composite material. It is thought that it will be possible to apply C.F.E.C. to both medical engineering for modeling biological tissue and to the aerospace industry as an orthotropic photoelastic material.
