Abstract

Photoelastic studies were conducted on a simply supported beam of uniform cross section made of Hysol 8530 material and subjected to central transverse impact by .402" diameter steel and aluminum spheres. The effects of impact angle, beam span, sphere mass, as well as impact velocity on the bending stress were investigated. Material constants, modulus of elasticity, and material fringe value for Hysol 8530 were determined for both static and dynamic loading conditions. Experimental results were presented. A Dynafax high speed camera (0-26, 000 frames/sec) was used to record the beam's dynamic birefringence. Comparisons with theory and other investigations were also made.
