Abstract

Graphene nanomaterial-reinforced zirconia matrix composites (ZMCs) have demonstrated exceptional load-carrying capabilities, even in the demanding conditions demanded by new applications. The main reason for their outstanding mechanical performance, particularly their resilience to cracks, is the diversity of their microstructures. Composites using intentionally scattered graphene exhibit exceptional resilience to catastrophic failure due to toughening mechanisms external to the matrix. Our investigation of the fractured behavior of these nanocomposites is insufficient, and the complex energy dissipation mechanism at the interface between the reinforcement and the matrix is hindering our progress in creating more robust and tougher ZMCs. To overcome these constraints, we study energy dissipation and fracture deflection in nanocomposites using an enhanced cohesive shear-lag approach. Nanocomposites’ toughening is controlled by interfacial debonding and friction, which are taken into consideration in this novel model. Our study will inform you how to maximize the toughening effects of ZMCs.
