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…

A variational phase-field model for anisotropic fracture accounting for multiple cohesive lengths
Angela Maria Fajardo Lacave, Francesco Vicentini, Fabian Welschinger +1
We propose a novel variational phase-field model for fracture in anisotropic materials. The model is specifically designed to allow a more flexible calibration of crack nucleation…

Variational phase-field modeling of cohesive fracture with flexibly tunable strength surface
Francesco Vicentini, Jonas Heinzmann, Pietro Carrara +1
Variational phase-field models of brittle fracture are powerful tools for studying Griffith-type crack propagation in complex scenarios. However, as approximations of Griffith's th…
