Strength of tool materials under single impact loading

The article describes a new method and an installation for determining the strength and crack resistance of brittle tool materials under single impact loading. It also presents data on the metrological characteristics of the installation. The installation is suitable for determining the tensile strength and crack resistance of a number of ceramics, hard alloys of the tungsten-cobalt group, and of polycrystals of superhard materials. The effect of the loading rate on the strength of some materials is demonstrated.Translated from Problemy Prochnosti, No. 7, pp. 33–40, July, 1992.
