Multiple-phase-field modeling for fracture of composite materials

Fracture behavior of composite materials is a challenge in numerical simulations due to the heterogeneity introduced by reinforcements. Based on the phase-field fracture model, a multiple-phase-field ductile fracture model is developed by using different phase field descriptors to characterize multiple cracking behaviors, involving different fracture mechanism such as brittle fracture and ductile fracture for composite materials. A novel...
