Comparison Between Two Types of Seismic Tests of Racking Systems
(2021-09)
Article
Open AccessThis paper is the result of both experimental and numeric analyses on pallet rack components. Two cyclic testing protocols for beam-end connectors of adjustable racking systems are compared; such experiments are named as ... -
Warpage analysis and control of thin-walled structures manufactured by laser powder bed fusion
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-05)
Article
Open AccessThin-walled structures are of great interest because of their use as lightweight components in aeronautical and aerospace engineering. The fabrication of these components by additive manufacturing (AM) often produces ... -
Analysis of a stabilized finite element approximation for a linearized logarithmic reformulation of the viscoelastic flow problem
(2021-02)
Article
Open AccessIn this paper we present the numerical analysis of a finite element method for a linearized viscoelastic flow problem. In particular, we analyze a linearization of the logarithmic reformulation of the problem, which in ... -
Simulations of landslide wave generation and propagation using the particle finite element method
(Wiley, 2020-06)
Article
Open AccessIn this study, the impulse waves generated by highly mobile slides in large-scale flume experiments are reproduced numerically with the Particle Finite Element Method (PFEM). The numerical technique combines a Lagrangian ... -
A fully Lagrangian formulation for fluid-structure interaction problems with free-surface flows and fracturing solids
(2021-07)
Article
Restricted access - publisher's policyThis paper presents a novel coupled formulation for fluid-structure interaction (FSI) problems involving free-surface fluid flows, fracture phenomena, solid mutual contact and large displacements. The numerical formulation ... -
Failure pressure analysis of a nuclear reactor prestressed concrete containment building
(Elsevier, 2021-06)
Article
Restricted access - publisher's policyThe failure analysis of an existing and operational nuclear power plant reactor containment building subjected to an accident internal pressure is studied in this paper. The computation is based on the Finite Element Method ... -
Modeling of the effect of the building strategy on the thermomechanical response of Ti-6Al-4V rectangular parts manufactured by laser directed energy deposition
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-12)
Article
Open AccessPart warpage and residual stress are two of the main challenges for metal additive manufacturing (AM) as they result in lower geometric precision and poor mechanical properties of the products. This work investigates the ... -
Partitioned strong coupling of discrete elements with large deformation structural finite elements to model impact on highly flexible tension structures
(Hindawi, 2020-11)
Article
Open AccessThis article presents a staggered approach to couple the interaction of very flexible tension structures with large deformations, described with the finite element method (FEM), and objects undergoing large, complex, and ... -
Field-to-field coupled fluid structure interaction: a reduced order model study
(2021-01)
Article
Open AccessThe standard Fluid-Structure Interaction (fsi) coupling, that uses as unknowns velocity and pressure for the fluid and displacements for the solid, is compared against two novel types of coupling, the first one a three-field ... -
Systemized structural predesign method for selective racks
(2020-12)
Article
Open AccessThis paper presents a simplified stability-based method for practical structural predesign of down-aisle unbraced frames of selective racks. Given the uniformity of actual racks, only a single upright and its adjoining ...
