Dynamic photoelastic investigation of interaction of stress waves with running cracks - A photoelastic study of interaction of stress waves with running cracks is conducted to investigate the influence of crack-wave interaction on crack-propagation behavior and crack branching

Dynamic photoelasticity in conjunction with high-speed photography was utilized in experiments to study the interaction of stress waves with a running crack. Experimental data were analyzed to study the effect of wave scattering about a moving crack tip. The results indicated a strong influence of stress waves on crack-propagation behavior and crack branching. © 1981 Society for Experimental Mechanics, Inc
