On phase-field regularization in dynamic fracture with brittle and cohesive formulations
Jonas Heinzmann, Francesco Vicentini, Pietro Carrara +1
The paper compares three phase‑field fracture models—brittle with stiffness degradation, brittle with stiffness and density degradation, and a cohesive formulation extended to dyna…
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…
Discovery of Hyperelastic Constitutive Laws from Experimental Data with EUCLID
Arefeh Abbasi, Maurizio Ricci, Pietro Carrara +4
We assess the performance of EUCLID, Efficient Unsupervised Constitutive Law Identification and Discovery, a recently proposed framework for automated discovery of constitutive law…
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…
Phase-field modeling of elastic microphase separation
Hamza Oudich, Pietro Carrara, Laura De Lorenzis
We propose a novel phase-field model to predict elastic microphase separation in polymer gels. To this end, we extend the Cahn-Hilliard free-energy functional to incorporate an ela…
Fracture in concrete: X-ray tomography with in-situ testing, digital volume correlation and phase-field modeling
Akanksha Mishra, Pietro Carrara, Michele Griffa +1
We test and simulate the mesoscopic cracking behavior of specimens made of a standard concrete mixture. To this end, we combine stable wedge-splitting fracture experiments performe…
