A COMPARISON OF STATIC AND DYNAMIC PROPERTIES OF PHOTOELASTIC MATERIALS

Abstract

The dynamic values of the modulus of elasticity and photoelastic fringe constant of Homalite 100 and ten epoxy resins were determined. Of these eleven materials, it was found that five exhibited desirable dynamic properties including two materials which exhibited no appreciable changes in fringe constant. Consequently a static calibration on these materials can be used for dynamic experiments with a high degree of accuracy. Included in this group of five materials were three materials which can be purchased in precast shapes, thus enabling laboratories without casting facilities to obtain suitable materials for dynamic photoelastic experiments.
