Influence of matrix strength and damage accumulation on the mechanical response of a particulate metal matrix composite

The starin hardening characteristics of a metal matrix, for various ageing treatments, has been found to influence the strength of a SiC particulate MMC. Experimental observations of this effect have been successfully compared with theoretical predictions using a self-consistent model based on Eshelby's equivalent inclusion method. The level of damage accumulation has been measured using modulus change experiments. The modulus is found to …
