Analytical, Computational and Experimental Investigations on Stress Wave Propagation

Abstract

Wave phenomena in intensely loaded bodies are often paradoxical and unexpected. They are evoked by stress wave interactions and depend substantially on actual material properties, body shapes and dimensions, friction, etc. Their proper understanding is indispensable for the reliable evaluation of the quality of various technologies as nuclear reactor safety, armour penetration, nondestructive testing, etc. The paper presents a survey of analytical, computational and experimental techniques and methods being employed for the solutions of stress wave propagation problems in solids.

The role of the coefficient of restitution on impact problems in multi-body dynamics

“…The investigation of the micro-mechanical processes on the fast time scale requires measurement devices which are capable of capturing the highfrequency wave phenomena. Many different techniques for investigating wave propagation are summarized in Al-Mousawi [67] and Höschl et al [68]. Often strain-gauges are used for measuring wave propagation in rods [69] and can also be used for impact investigation as shown by Barton et al [70], Cunningham and Goldsmith [71] and Hu et al [72].…”
