Abstract

Elastic constant both on along-fiber (AF) and cross-fiber (CF) direction of two kinds of bamboo charcoal are measured using digital speckle correlation method (DSCM). Fracture toughness of two kinds of SiC which consist of bamboo charcoal are analyzed by using DSCM and conventional Loading method. The experiment shows that the results measured by DSCM are in accordance with the results measured by using conventional Loading method. Moreover, we can conclude from the results that bamboo charcoal is a kind of anisotropic material, SiC remains the anisotropic property of bamboo charcoal.
