Abstract
Methods of photoelasticity and grids in conjunction with low-modulus materials were developed as means for studying wave propagation in solids. A number of low modulus materials were studied and Elysol 8705 (a urethane rubber compound) was selected as the model material. A complete study of its mechanical and optical properties was made under static and dynamic loadings. The modulus of elasticity was dependent on the rate of loading and the specific energy loss for the material was about 10% for the stress ranges associated with photoelastic determinations. The specific problems studied included struts subjected to axial impact, disks subjected to diametrical impact, plates subjected to explosive loads on the boundary, and wave propagation past various geometric discontinuities in rectangular bars.
