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…
Reduced and All-at-Once Approaches for Model Calibration and Discovery in Computational Solid Mechanics
Ulrich Römer, Stefan Hartmann, Jendrik-Alexander Tröger +4
In the framework of solid mechanics, the task of deriving material parameters from experimental data has recently re-emerged with the progress in full-field measurement capabilitie…
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…
Enhanced Floating Isogeometric Analysis
Helge C. Hille, Siddhant Kumar, Laura De Lorenzis
The numerical simulation of additive manufacturing techniques promises the acceleration of costly experimental procedures to identify suitable process parameters. We recently propo…
