Characterization of Confined Strength of Intact and Damaged B4C and SiC
Abstract
This report summarizes the characterization work performed on intact and predamaged boron carbide and silicon carbide tested in compression. Confined compression testing was conducted using a pressure vessel or using a thick steel confining sleeve. Optical and stereomicroscopy were used to evaluate, document, and provide insights to the damage morphology. The effect of pressure (up to 2 GPa hydrostatic pressure) on the strength of the two materials is quantified. The failure curves obtained are presented and written as Drucker-Prager and Mohr-Coulomb failure criteria. Results are discussed and compared to the literature. It is shown that data obtained with very different techniques (confined compression, plate impact and divergent plate impact) are in reasonably good agreement.
