| Abstract: | The dynamic values of the modulus of elasticity and photoelastic fringe constant of Homalite 100 and ten epoxy resins were determined. Of those tested, it was found that five exhibited desirable dynamic properties including two materials which exhibited no appreciable change in fringe constant. 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. |
