Experimental and numerical study of adhesively and bolted connections of pultruded GFRP I-shape profiles
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-03)
Article
Open AccessRecent developments indicate that the application of pultruded FRP profiles has been continuously growing in the construction industry. Generating more complex structures composed of pultruded FRP profiles requires joining ... -
Combination of acoustic emission and vibratory measure-ments to characterize an ultrasonic vibration assisted ball burnishing tool for a lathe
(2021-07-14)
Article
Open AccessIn this paper, a resonant system that produces a movement of low amplitude and ultrasonic frequency is used to achieve the vibration assistance in a ball-burnishing process. A full vibration characterization of this process ... -
Residual stresses control in additive manufacturing
(MDPI, 2021-12)
Article
Open AccessResidual stresses are one of the primary causes for the failure of parts or systems in metal additive manufacturing (AM), since they easily induce crack propagation and structural distortion. Although the formation of ... -
Topological derivative-based topology optimization of incompressible structures using mixed formulations
(2022-02)
Article
Restricted access - publisher's policyIn this work an algorithm for topological optimization, based on the topological derivative concept, is proposed for both nearly and fully incompressible materials. In order to deal with such materials, a new decomposition ... -
Ductility improvement of adjustable pallet rack speed-lock connections: Experimental study
(2022-01)
Article
Open AccessThis paper presents seismic cantilever monotonic and cyclic tests of speed-lock (boltless) beam-to-upright con-nections of adjustable pallet rack systems; the objective of the monotonic tests is to obtain the bounds that ... -
Numerical investigation on a seismic testing campaign on adjustable pallet rack speed-lock connections
(Elsevier, 2022-02)
Article
Open AccessThis paper presents numerical simulations of a suite of cantilever seismic tests of speed-lock connections between beam and upright members of adjustable pallet rack systems. The tested specimens differ in the endplate-to-beam ... -
On the numerical study of fatigue process in rail heads by means of an isotropic damage based high-cycle fatigue constitutive law
(Elsevier, 2022-01)
Article
Restricted access - publisher's policyThe fatigue phenomenon has been historically related to the railway industry. Nowadays, thanks to the high quality of the materials used, most of the recorded problems have been overcome although there are still degradation ... -
Simulation-assisted investigation on the formation of layer bands and the microstructural evolution in directed energy deposition of Ti6Al4V blocks
(2021-09)
Article
Restricted access - publisher's policyAdditive manufacturing (AM) of titanium alloy entails severe microstructural heterogeneity and layer bands due to diverse thermal histories. While the thermal-microstructure relationship in AM has been reported, the details ... -
Numerical simulation of non-isothermal viscoelastic fluid flows using a VMS stabilized finite element formulation
(2021-10)
Article
Restricted access - publisher's policyThe effect of temperature in viscoelastic fluid flows is studied applying a stabilized finite element formulation based on both a standard and a log-conformation reformulation (LCR), and the Variational Multiscale (VMS) ... -
Experimental and numerical study of shear interface response of hybrid thin CFRP–concrete slabs
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-09-09)
Article
Open AccessHybrid slabs made of carbon-fiber-reinforced polymer (CFRP) and concrete provide a solution that takes advantage of the strength properties of both materials. The performance of the system strongly depends on the CFRP–concrete ... -
Flexible fiber fabric for FRP–concrete connection of thin hybrid slabs
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-08-26)
Article
Open AccessIn order to combat corrosion issues, several studies on progressively replacing steel reinforcement elements with composite ones have been conducted in recent years. Hybrid steel– concrete thin slabs in which the steel ... -
Substrate design to minimize residual stresses in Directed Energy Deposition AM processes
(Elsevier, 2021-04)
Article
Open AccessThis paper proposes a strategy to optimize the design of the substrate structures used in Additive Manufacturing (AM) by Directed Energy Deposition (DED) to minimize the residual stresses induced by this fabrication process. ...
