Abstract This work presents a novel double-phase-field formulation to characterize the distinct damage mechanisms
and the mixed-mode cohesive fracture behaviors in fiber-reinforced composites (FRC). A hybrid phase field
formulation is first proposed to derive the phase field and stress through distinct energy functionals. Then,
the phase field degradation function and material damaged stiffness are properly defined based on the
unique failure mechanisms, which enable the derivation of the embedded Hashin failure criteria for fiber
and matrix failures in FRC respectively. Furthermore, the mixed-model cohesive law with linear softening is
analytically derived within the phase field framework More >
