Phase-field modeling of anisotropic brittle fracture including several damage mechanisms
Computer Methods in Applied Mechanics and Engineering, 2018 The present paper aims at modeling complex fracture phenomena where different damaging mechanisms are involved. For this purpose, the standard one-variable phase-field/gradient damage model, able to regularize Griffith’s isotropic brittle fracture ...
