Impact Resistance of Structural Ceramics. Part II. Ballistic Tests.

Abstract

Two mechanisms can lead to failure of ceramics under impact, (1) failure due to flexural stresses, and (2) failure due to Hertzian type cracks introduced locally by the impactor. These mechanisms have been studied in silicon nitride, silicon carbide, and aluminum oxide ceramics using 200-1000 f/s BB ball steel impactors and different types of specimen support. The critical velocities for flexural failure and Hertzian damage of 1 x 1 x 0.2 inch plates were determined. (Author)
