Nanosecond shock wave-induced surface acoustic waves and dynamic fracture at fluid-solid boundaries

Dynamic interactions between nanosecond shockwave induced by leaky Rayleigh wave and evanescent wave at water-glass boundaries are investigated experimentally and numerically. This interaction generates the maximum impulsive tension in the solid, leading to circular crack formation, that is consistent with previous theoretical predictions. The orientation of the ring fracture extension into the solid also follows closely with the trajectory of the local maximum tensile stress distribution.
