Abstract

The propagation and reflections of a shock wave induced by the focusing of a high power pulsed laser (40 J, 10 ns) on a substrate of chromium coated by copper yield traction at the interface and can lead to debonding. The LAser Shock Adherence Test (LASAT) is based on the analysis of the rear face velocity profiles differences, measured by a VISAR, when the laser energy reaches the debonding threshold. The relevance of these differences with the system copper/chromium is discussed. By comparison with numerical simulation of shock wave propagation with SHYLAC code, the adhesion level of this system is deduced, including the dynamic effects.
