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
Restricted access - publisher's policyThe 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 ... -
Structural analyses of orthogrid fuselage panel for integrated Ku-band SatCom antenna
(International Centre for Numerical Methods in Engineering (CIMNE), 2019)
Conference lecture
Open AccessThe aim of this work is to describe the structural analysis of a multifunctional aircraft fuselage panel. The structure of the panel has an embedded antenna tiles. The panel consists of UniDirectional (UD) carbon fibre ... -
Solution of transient viscoelastic flow problems approximated by a term-by-term VMS stabilized finite element formulation using time-dependent subgrid-scales
(2020-08)
Article
Restricted access - publisher's policySome finite element stabilized formulations for transient viscoelastic flow problems are presented in this paper. These are based on the Variational Multiscale (VMS) method, following the approach introduced in Castillo ... -
Combination of an adaptive remeshing technique with a coupled FEM–DEM approach for analysis of crack propagation problems
(Springer, 2020-07)
Article
Open AccessThis paper presents an enhanced coupled approach between the finite element method (FEM) and the discrete element method (DEM) in which an adaptive remeshing technique has been implemented. The remeshing technique is based ... -
Solution of Navier–Stokes equations on a fixed mesh using conforming enrichment of velocity and pressure
(Springer, 2020-01)
Article
Open AccessSimulation of fluid flows of multi-materials is an intriguing topic in computational mechanics. Capturing the physics of the interface between different materials poses a challenge because of the discontinuities that may ... -
An accurate nonlocal bonded discrete element method for nonlinear analysis of solids: application to concrete fracture tests
(Springer, 2020-05)
Article
Open AccessWe present a numerical procedure for elastic and nonlinear analysis (including fracture situations) of solid materials and structures using the discrete element method. It can be applied to strongly cohesive frictional ... -
Fluid structure interaction by means of variational multiscale reduced order models
(2020-06)
Article
Open AccessA reduced order model designed by means of a variational multiscale stabilized formulation has been applied successfully to fluid-structure interaction problems in a strongly coupled partitioned solution scheme. Details ... -
Logarithmic conformation reformulation in viscoelastic flow problems approximated by a VMS-type stabilized finite element formulation
(2019-09)
Article
Restricted access - publisher's policyThe log-conformation reformulation, originally proposed by Fattal and Kupferman (2004), allows computing incompressible viscoelastic problems with high Weissenberg numbers which are impossible to solve with the typical ...
