Simulation of Impact and Fragmentation of SiC Skeleton
2021
Silicon carbide foam is a promising material for high-temperature use because
it has excellent thermal shock resistance and strength, low thermal
conductivity, and excellent chemical resistance. Up till now SiC foam was
analyzed under quasi-static compression and 4- and 3-point bending. This paper
attempts for the first time to numerically analyze the SiC foam properties under
impact conditions. Using the peridynamical approach it was possible to describe
damage initiation, its dynamical growth, and the final fragmentation of the
foam. The major conclusions resulting from the analysis are that for high impact
velocities damage initiates much earlier compared to low-velocity impact, and
the modes of failure are qualitatively different.
