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…
Interior-point methods for the phase-field approach to brittle and ductile fracture
Jef Wambacq, Jacinto Ulloa, Geert Lombaert +1
The governing equations of the variational approach to brittle and ductile fracture emerge from the minimization of a non-convex energy functional subject to irreversibility constr…
Phase-field modeling of fatigue coupled to cyclic plasticity in an energetic formulation
Jacinto Ulloa, Jef Wambacq, Roberto Alessi +2
This paper presents a modeling framework to describe the driving mechanisms of cyclic failure in brittle and ductile materials, including cyclic plasticity and fatigue crack growth…
