“…Following a simple, so-called acoustic approximation, and assuming that the thickness of the coating and the duration of the loading pulse are ideally combined to ensure that maximum tension is induced exactly at the interface location, a rough estimate of the interfacial strength would be σint ≈ ½ ρAg CAg Δu (1) where ρAg and CAg are the density and bulk sound velocity in the Ag layer, respectively [17].…”

“…If the local tensile stress overcomes the interface strength, debonding occurs, new free surfaces are created, and subsequent stress relaxation produces recompression waves. In favorable cases, the detection of such waves in velocity records and their analysis may provide an estimate of the bonding strength at the interface [17]. This technique requires (i) planar shock loading of controlled amplitude and duration on the substrate side, (ii) accurate time-resolved measurement of the free surface velocity of the coating, opposite to the loaded spot, (iii) a correct knowledge of the materials constituting both layers, including the density and sound velocity in the coating material, and (iv) an adhesive strength at the interface lower than the cohesive strength (so-called spall strength) of these constituents.…”
