Abstract

Nanoductility induced crack nucleation mechanism mediated by a single dislocation core is revealed in a 300 million-atom molecular dynamics simulation of shocked silicon carbide ceramic. The atomistic damage mechanism involves dynamic transitions between clearly delineated regimes-from shock-induced structural transformation to plastic deformation to brittle fracture. Such atomistic understanding may help in the design of nanocrack suppression strategies to realize predictive modeling of complex damage processes in high-performance ceramics. © 2010 American Institute of Physics.
