Gamma convergence for a phase-field cohesive energy
Eleonora Maggiorelli, Matteo Negri, Francesco Vicentini +1
Reproducing the key features of fracture behavior under multiaxial stress states is essential for accurate modeling. Experimental evidence indicates that three intrinsic material p…

AT1 fourth-order isogeometric phase-field modeling of brittle fracture
Luigi Greco, Eleonora Maggiorelli, Matteo Negri +2
A crucial aspect in phase-field modeling, based on the variational formulation of brittle fracture, is the accurate representation of how the fracture surface energy is dissipated…
