Plane detonation waves produced in the explosive PETN with use of wire-row explosion technique for initiation were transferred into the metallic plate specimens generating spall failure due to the interaction of triangular release waves. Recent study has revealed that slanting side surface of specimens change the spall damage phenomena, and machining slanting surfaces sophisticatedly on the free surface yields a possibility to reduce spall failure dramatically. v-notch rows are produced parallel to the side lines by electro-discharge machining at the free surfaces of provided quadratic plate specimens of stainless steel SUS304 and aluminum alloy A2024, and the explosively driven plane shock waves are transferred from the other surfaces. In order to investigate the inclined surface effect, the angles and the depths of the v-notches are varied as parameters, and basic quadratic plate specimens with both plain smooth surfaces are tested for comparison.
