Abstract
Ceramic circular plates of pressureless sintered silicon carbide were impacted with steel balls, and the experimental results were compared with quasi-static theoretical analyses and dynamic fracture analyses by the FEM code, DYNA 3D. It was shown that a simplified method of quasi-static plastic analysis, proposed by the authors, considerably simulates the plastic behavior of steel balls at impact. Moreover, a numerical method of ceramic fracture analysis, also proposed by the authors, was shown to be able to represent experimental failure modes of ceramic plates.
