Conference lecture
Open AccessIn this paper iron powders with two oxygen content (0.2 and 0.6% wt.) have been mechanically milled and consolidated by hot static pressing at different temperatures to obtain different grain sizes. At lower temperatures ... -
Medición de tensiones internas de materiales metálicos laminados en geometría cilíndrica y cónica
(Universitat Politècnica de Catalunya, 2022-02-02)
Bachelor thesis
Open AccessLes tensions residuals son tensions presents a una peça d’un material, sense l’aplicació d’un esforç extern. La presencia d’aquestes tensions pot suposar canvis en la integritat estructural de les peces, afectant a les ... -

Model teòric i verificació experimental de la deformació transversal del formigó sota càrrega cíclica
(Universitat Politècnica de Catalunya, 2010-05-18)
Minor thesis
Open AccessHabitualment, el càlcul de seccions de formigó armat s'aborda suposant que el material està sotmès a un estat de tensió uniaxial. No obstant això, realment, en un gran nombre de casos el formigó es troba en un estat tensional ... -
Modelització del deflectòmetre d'impacte amb el mètode dels elements finits i les partícules
(Universitat Politècnica de Catalunya, 2011-02-15)
Minor thesis
Open AccessEl deflectòmetre d’impacte segurament és l’aparell més utilitzat per realitzar assaigs no destructius dels ferms. Els enginyers utilitzen el deflectròmetre d’impacte per estimar els mòduls elàstics de les diferents capes ... -
Non-diffusional growth mechanism of I1 basal stacking-faults inside twins in hcp metals
(2019-11)
Article
Open AccessDeformation twins in magnesium exhibit considerable densities of I1 basal-plane stacking-faults. Since these faults generally transect their host twin, they presumably lengthen concommitantly with boundary migration during ... -
Numerical Simulation on Buckling Failure of the Masonry Load Bearing Walls
(Universitat Politècnica de Catalunya, 2010-07-21)
Master thesis
Open AccessMasonry load bearing wall subjected to vertical concentric and eccentric loading may collapse through instability. The buckling behavior of masonry load bearing wall of different slenderness ratio were investigated via ... -
On chiral effects in strain gradient elasticity
(2016-07-01)
Article
Open AccessThis paper is concerned with the problem of uniformly loaded bars in strain gradient elasticity. We study the deformation of an isotropic chiral bar subjected to body forces, to tractions on the lateral surface and to ... -

On the theory of chiral plates and associated system of Timoshenko–Ehrenfest type
(2021-09)
Article
Restricted access - publisher's policyThe chiral effects cannot be described by means of the classical theory of elasticity. In this paper we study the thermoelastic deformation of chiral plates in the context of the strain gradient theory of thermoelasticity. ... -

Conference report
Open AccessLe comportement d’un acier à haute résistance lors d’un processus de forge à chaud a été étudié para des essais de compression uniaxiale à haute température sur une large gamme de vitesse de ... -
Physical model to predict the ball-burnishing forces
(2011-09-23)
Article
Restricted access - publisher's policyIn this paper, we have developed a physical model to predict the forces of the ball burnishing. The models have been constructed on the basis of the plasticity theory. During the model development we have figured out the ... -
Plastic deformation induced anisotropy in metallic glasses: A molecular dynamics study
(2017-06-15)
Article
Open AccessThe atomic structure of a Cu13Ni34Pd53 metallic glass was studied by molecular dynamics simulation at different temperatures along a shear deformation cycle. A simulation box of 1 million atoms was deformed in the x axis ... -
