title = "Threshold of ring crack initiation on CVD-SIC under particle impact",
abstract = "This study examines the threshold of ring crack initiation to provide the fundamental and morphological cracking behavior of impact damage on pure β-SiC structure in comparison of other brittle material such as soda-lime glass. Particle impact test was carried out by using 2 mm spherical steel ball as a projectile at room temperature. For the polished CVD-SiC, the diameter of outermost ring crack increase linearly with the increase of impact velocity. Cracking patterns were examined and schematically established for the test materials versus impact energy. Threshold of ring crack initiation on polished CVD-SiC was about 0.7E-03 J. Radial cracks were observed over 2.15E-02 J at the first time in both rough and smooth surface of CVD-SiC The result of outermost ring crack in two surface finish were almost similar to a certain impact velocity but dramatic behavior was also observed. The threshold of ring crack initiation is important significance in order to prevent the fracture of components.",
