Dynamic analysis with point-masses of perforated pallet rack structural members by means of the Generalized Beam Theory
(2024-06)
Article
Open AccessThis paper presents two different formulations for introducing point-masses into a dynamic problem using the Generalized Beam Theory (GBT) method. The first one implies placing a point-mass at a beam-node (with or without ... -
Modelling of pallet rack connections by means of a geometrically nonlinear analysis based on the Generalized Beam theory
(2024-11)
Article
Open AccessThis paper presents a formulation to reproduce the main connections of pallet rack structures by means of a Generalized Beam Theory analysis. Different approaches to modelling the upright-to-brace and upright-to-beam ... -
Global analysis of adjustable pallet rack down-aisle frames using the generalised beam theory
(Multidisciplinary Digital Publishing Institute, 2024-06-25)
Article
Open AccessA global analysis of a rack frame conducted using the Generalised Beam Theory (GBT) is presented. This study specifically focuses on a down-aisle frame, showing the particular characteristics of this type of structure, ... -
A chimera method for thermal part-scale metal additive manufacturing simulation
(Elsevier, 2024-11)
Article
Restricted access - publisher's policyThis paper presents a Chimera approach for the thermal problems in welding and metallic Additive Manufacturing (AM). In particular, a moving mesh is attached to the moving heat source while a fixed background mesh covers ... -
A coarse-grained bonded particle model for large-scale rock simulation
(Elsevier, 2024-10)
Article
Open AccessFor solving the computationally intensive problem encountered by the discrete element method (DEM) in simulating large-scale engineering problems, it is essential to establish a numerical model that can effectively simulate ... -
The Shifted Boundary Method in Isogeometric Analysis
(Elsevier, 2024-10)
Article
Open AccessThis work presents a novel application of the Shifted Boundary Method (SBM) within the Isogeometric Analysis (IGA) framework, applying it to two-dimensional and three-dimensional Poisson problems with Dirichlet and Neumann ... -

(Elsevier, 2024-09)
Article
Open AccessThis work is the second of a two-part research project focused on modeling solid-shell elements using a stabilized two-field finite element formulation. The first part introduces a stabilization technique based on the ... -
A high cycle fatigue numerical framework for component-level virtual fatigue testing: application to a light-duty vehicle lower control arm
(Elsevier, 2024-07)
Article
Open AccessThe conception of lightweight structures constitutes a fundamental design principle of the contemporary automotive industry. In this sense, the chassis is one of the areas with major potential for the implementation of ... -
Hydromechanical embedded finite element for conductive and impermeable strong discontinuities in porous media
(Elsevier, 2024-08)
Article
Open AccessThe pore pressure inside oil and gas reservoirs compartmentalized by sealing faults increases during injection processes. The rise in the pore pressure can induce fault reactivation, leading to hydraulic issues such as ... -
Stress–displacement stabilized finite element analysis of thin structures using solid-shell elements. Part I: On the need of interpolating the stresses
(Elsevier, 2024-09)
Article
Open AccessThis work studies the solid-shell finite element approach to approximate thin structures using a stabilized mixed displacement-stress formulation based on the Variational Multiscale framework. The work is divided in two ... -
Embedded Finite Element formulation for fluid flow in fractured porous medium
(Elsevier, 2024-07)
Article
Restricted access - publisher's policyThe presence of discontinuities, such as fractures or geological faults, can significantly influence the fluid flow in a porous medium. In general, the discontinuities can act as preferential flow paths. However, depending ... -
On the efficient and accurate non-linear computational modeling of multilayered bending plates. State of the art and a novel proposal: the 2D+ multiscale approach
(2024-07)
Article
Open AccessAfter conducting a comprehensive historical review of presently established methods for computational modeling of multilayered bending plates, the present work introduces a novel 2D multiscale strategy, termed the 2D+ ...
