Multiscale investigations into the fracture toughness of SiC/graphene composites: Atomistic simulations and crack-bridging model

Experiments showed that the fracture toughness of silicon carbide (SiC) ceramics can be enhanced by adding graphene-based fillers. To understand the toughening mechanism and thoroughly explore the toughening potential, we used a multiscale approach combined with molecular dynamics (MD) simulations to theoretically study the correlation between the toughening effect and the microstructure parameters of SiC/graphene lamellar composite.
