Abstract The phase field approach to fracture originates from the variational formulation of brittle fracture proposed
by Francfort and Marigo. The regularized version of the latter formulation by Bourdin et al. is also dubbed
the phase field approach to fracture. Compared with explicit crack methods such as the extended finite
element method, the phase field approach to fracture does not require additional criteria for crack
simulation and can naturally simulate complex fracture behaviors such as crack initiation, propagation,
branching and merging with a fixed mesh and fixed shape functions. This work examines the energy
relations in the phase field approach to… More >
