As an application of the phase field model for crack propagation in elastic body, chemical-diffuse crack growth model with the effect of the hydrogen embrittlement is considered. Numerical results show the difference of crack path between data wit...
We investigate a physical characterization of the gradient flow structure of
variational fracture models for brittle materials: a Griffith-type fracture
model and an irreversible fracture phase field model. We derive the
Griffith-type fracture mod...
Two examples of extention of crack growth model with phase field approach are derived. A crack growth model for visco-elastic material is introduced from exctended free energy which add effect of Maxwell fluid. Another model with effect of H-embri...
