Energy-consistent dynamic fracture phase field models: unilateral constraints and finite element simulations
A dynamic phase-field fracture model with a unilateral contact condition produces shear-driven crack growth in 2D fault-like simulations, while the standard model produces nonphysical kink cracks.
