| Abstract Scope |
Metal matrix composites (MMCs) exhibit complex fracture behaviors influenced by matrix properties, embedded particles, and their interfaces. Fracture initiation can occur within hard particles, at the particle-matrix interface, or in the surrounding matrix, depending on particle size, matrix stiffness, and crystallographic orientation. Hard particles often lead to stress concentrations at the interface, while soft particles deform more easily, resulting in matrix yielding and interface debonding. This study presents a coupled phase-field and crystal plasticity model to predict fracture mechanisms in MMCs reinforced with hard and soft particles. The phase-field method captures crack evolution, while the crystal plasticity framework accounts for anisotropic plastic deformation influenced by crystallographic orientation. By simulating damage propagation under various loading conditions, this model generates detailed data that can be used to develop machine learning algorithms for faster and more efficient predictions of material failure.
