Accés restringit per política de l'editorialThis paper presents an investigation on the ability of two alternative FE-based numerical methods to simulate the in-plane strength and collapse of brick masonry shear walls. The methods considered consist of a meso-model, ... -
On the discrete constitutive models induced by strong discontinuity kinematics and continuum constitutive equations
(2000-11)
Article
Accés obertOn the basis of continuum constitutive models (stress vs. strain), the introduction of strong discontinuity kinematics (considering jumps in the displacement fields across a discontinuity interface) induces projected ... -
On the equivalence between traction- and stress-based approaches for the modeling of localized failure in solids
(2015-09)
Article
Accés obertThis work investigates systematically traction- and stress-based approaches for the modeling of strong and regularized discontinuities induced by localized failure in solids. Two complementary methodologies, i.e., ... -
On the strong discontinuity approach in finite deformation settings
