Finite element analysis and experimental validation of the thermomechanical behavior in laser solid forming of Ti-6Al-4V
(Elsevier, 2018-05)
Article
Open AccessA three-dimensional (3D) thermomechanical coupled model for Laser Solid Forming (LSF) of Ti-6Al-4V alloy has been calibrated through experiments of 40-layers metal deposition using different scanning strategies. The ... -
On the feasibility of the computational modelling of the endoluminal vacuum-assisted closure of an oesophageal anastomotic leakage
(2018-03)
Article
Open AccessEndoluminal vacuum-assisted closure (E-VAC) is a promising therapy to treat anastomotic leakages of the oesophagus and bowel which are associated with high morbidity and mortality rates. An open-pore polyurethane foam is ... -
Comparison of a Material Point Method and a Galerkin meshfree method for the simulation of cohesive-frictional materials
(2017-09)
Article
Open AccessThe simulation of large deformation problems, involving complex history-dependent constitutive laws, is of paramount importance in several engineering fields. Particular attention has to be paid to the choice of a suitable ... -
Approximating the Basset force by optimizing the method of van Hinsberg et al.
(2018-01)
Article
Open AccessIn this work we put the method proposed by van Hinsberg et al. [29] to the test, highlighting its accuracy and efficiency in a sequence of benchmarks of increasing complexity. Furthermore, we explore the possibility of ... -
Appraisement of planar, bending and twisting cracks in 3D with isotropic and orthotropic damage models
(Springer, 2018-03)
Article
Open AccessThis paper discusses the modeling of cracking in quasi-brittle materials using isotropic and orthotropic damage constitutive laws. A mixed strain/displacement finite element formulation is used, taking advantage of its ... -
A phase-field model for solute-assisted brittle fracture in elastic-plastic solids
(2018-03)
Article
Open AccessA phase-field theory of brittle fracture in elastoplastic solids hosting mobile interstitial solute species is developed in this paper. The theory, which is formulated within the framework of modern continuum mechanics, ... -
Cracking of quasi-brittle structures under monotonic and cyclic loadings: a d+/d- damage model with stiffness recovery in shear
(2018-03)
Article
Open AccessIn the present paper, a new d+/d- damage model apt for quasi-brittle materials is described and its validation is carried out considering unreinforced concrete, reinforced concrete and masonry elements.Two independent ... -
Tracking multi-directional intersecting cracks in numerical modelling of masonry shear walls under cyclic loading
(2018-05)
Article
Open AccessIn-plane cyclic loading of masonry walls induces a complex failure pattern composed of multiple diagonal shear cracks, as well as flexural cracks. The realistic modelling of such induced localized cracking necessitates the ... -
An enhanced finite element macro-model for the realistic simulation of localized cracks in masonry structures: a large-scale application
(Taylor & Francis, 2018-03)
Article
Open AccessFinite element macro-modelling approaches are widely used for the analysis of large-scale masonry structures. Despite their efficiency, they still face two important challenges: the realistic representation of damage and ... -
Numerical simulation of undrained insertion problems in geotechnical engineering with the Particle Finite Element Method (PFEM)
(Elsevier, 2017-02)
Article
Open AccessThe paper presents total-stress numerical analyses of large-displacement soil-structure interaction problems in geomechanics using the Particle Finite Element Method (PFEM). This method is characterized by frequent remeshing ... -
Generation of segmental chips in metal cutting modelled with the PFEM
(2017-09-01)
Article
Open AccessThe Particle Finite Element Method, a lagrangian finite element method based on a continuous Delaunay re-triangulation of the domain, is used to study machining of Ti6Al4V. In this work the method is revised and applied ... -
High performance reduced order modeling techniques based on optimal energy quadrature: application to geometrically non-linear multiscale inelastic material modeling
(2019-09)
Article
Open AccessA High-Performance Reduced-Order Model (HPROM) technique, previously presented by the authors in the context of hierarchical multiscale models for non linear-materials undergoing infinitesimal strains, is generalized to ...
