On the existence of representative volumes for softening quasi-brittle materials: a failure zone averaging scheme
(2010-11)
Article
Accés obertThe concept of the representative volume element (RVE) for softening materials is revised in this contribution. It is demonstrated by means of numerical simulations that there exists a sample which is statistically ... -
Homogenization-based multiscale crack modelling: from micro-diffusive damage to macro-cracks
(2011-02)
Article
Accés obertThe existence of a representative volume element (RVE) for a class of quasi-brittle materials having a random heterogeneous microstructure in tensile, shear and mixed mode loading is demonstrated by deriving traction–separation ... -

(John Wiley & sons, 2012-01)
Article
Accés obertA computational homogenization procedure for cohesive and adhesive crack modeling of materials with a heterogeneous microstructure has been recently presented in Computer Methods in Applied Mechanics and Engineering (2010, ... -
A fast and accurate method to solve the incompressible Navier-Stokes equations
(2013-02)
Article
Accés restringit per política de l'editorialPurpose: The purpose of this paper is to highlight the possibilities of a novel Lagrangian formulation in dealing with the solution of the incompressible Navier-Stokes equations with very large time steps. Design/meth ... -
RC structures cyclic behavior simulation with a model integrating plasticity, damage, and bond-slip
(Wiley, 2018)
Article
Accés obertCopyright © 2017 John Wiley & Sons, Ltd. The behavior of reinforced concrete structures under severe demands, as strong ground motions, is highly complex; this is mainly due to the complexity of concrete behavior and to ... -
Two-scale topology optimization in computational material design: an integrated approach

Article
Accés obertIn this work, a new strategy for solving multiscale topology optimization problems is presented. An alternate direction algorithm and a precomputed offline microstructure database (Computational Vademecum) are used to ... -
3D numerical models of FSW processes with non-cylindrical pin
(Taylor & Francis, 2015-06)
Article
Accés obertFriction Stir Welding (FSW) process is a relatively recent welding process (patented in 1991). FSW is a solid-state joining process during which materials to be joined are not melted. During the FSW process, the behaviour ... -
