On phase-field regularization in dynamic fracture with brittle and cohesive formulations
Jonas Heinzmann, Francesco Vicentini, Pietro Carrara +1
Phase-field models of fracture are widely used for simulating crack nucleation and propagation, yet the role of the phase-field regularization in the dynamic regime is not fully un…
Iterative convergence in phase-field brittle fracture computations: exact line search is all you need
Jonas Heinzmann, Francesco Vicentini, Pietro Carrara +1
Variational phase-field models of brittle fracture pose a local constrained minimization problem of a non-convex energy functional. In the discrete setting, the problem is most oft…
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…
Calibration and Validation of a Phase-Field Model of Brittle Fracture within the Damage Mechanics Challenge
Jonas Heinzmann, Pietro Carrara, Chenyi Luo +6
In the context of the Damage Mechanics Challenge, we adopt a phase-field model of brittle fracture to blindly predict the behavior up to failure of a notched three-point-bending sp…
Phase-field modeling of brittle fracture in heterogeneous bars
Francesco Vicentini, Pietro Carrara, Laura De Lorenzis
We investigate phase-field modeling of brittle fracture in a one-dimensional bar featuring a continuous variation of elastic and/or fracture properties along its axis. Our main goa…
