Endowing variational phase-field fracture models with custom strength criteria
Roberto Alessi, Matteo Brunetti, Roshan Udaram Patil +1
By now, several approaches have been proposed to endow phase-field fracture models with the ability to describe crack nucleation under multiaxial stress states. These include techn…
A micromechanics-based variational phase-field model for fracture in geomaterials with brittle-tensile and compressive-ductile behavior
Jacinto Ulloa, Jef Wambacq, Roberto Alessi +3
This paper presents a framework for modeling failure in quasi-brittle geomaterials under different loading conditions. A micromechanics-based model is proposed in which the field v…
A novel framework to model the fatigue behavior of brittle materials based on a variational phase-field approach
P. Carrara, M. Ambati, R. Alessi +1
A novel variational framework to model the fatigue behavior of brittle materials based on a phase-field approach to fracture is presented. The standard regularized free energy func…
