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…
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…
An adaptive acceleration scheme for phase-field fatigue computations
Jonas Heinzmann, Pietro Carrara, Marreddy Ambati +2
Phase-field models of fatigue are capable of reproducing the main phenomenology of fatigue behavior. However, phase-field computations in the high-cycle fatigue regime are prohibit…
