A simplified scheme for piezoelectric anisotropic analysis in human vertebrae using integral methods
(2018-06)
Article
Accés obertThis paper outlines a computational model for the analysis of the piezoelectric behaviour of the vertebral body remodelling process. Particular attention is paid to the algorithms for the simulation of the stress energy ... -
An implicit unsteady hydraulic solver for suspended cuttings transport in managed pressure wells
(Springer, 2018-08-29)
Article
Accés restringit per política de l'editorialWe present a simulation tool for transient events in complex hydraulic networks. The code includes modelling of the transport of suspended cuttings in near-vertical wells. An unstructured finite volume formulation with ... -
Seakeeping with the semi-Lagrangian particle finite element method
(Springer, 2017-07)
Article
Accés obertThe application of the semi-Lagrangian Particle Finite Element Method (SL–PFEM) for the seakeeping sim-ulation of the Wave Adaptive Modular Vehicle under spray generating conditions is presented. The time integration of ... -
A robust algorithm for implicit description of immersed geometries within a background mesh
(Springer, 2018-12)
Article
Accés obertThe paper presents a robust algorithm, which allows to implicitly describe and track immersed geometries within a background mesh. The background mesh is assumed to be unstructured and discretized by tetrahedrons. The ... -
Generating damping modification factors after artificial inputs in scenarios of local records scarcity
(2018-06-11)
Article
Accés obertThe damping modification factors are utilized to alter the design spectral ordinates for constructions whose damping differs significantly from 5%, this being the level that is routinely considered by most codes. Such ... -
New modifying truss model and numerical simulation of steel fiber reinforced concrete under pure torsion
(Elsevier, 2018-06-01)
Article
Accés restringit per política de l'editorialThis paper presents a new strut-and-tie model on steel fiber reinforced concrete (SFRC) members under uniform (Saint Venant) torsion. This truss model is intended to reproduce the structural behavior in ultimate limit ... -
Numerical study on the relevance of columns hidden failure modes in the seismic capacity of non-ductile RC Frames
(2018-04-11)
Article
Accés obertIn simplified seismic structural analyses, not all the deterioration modes are adequately considered. This work discusses the relation among the hidden failure modes of columns of non-ductile reinforced concrete building ... -
Interaction between an elastic structure and free-surface flows: experimental versus numerical comparisons using the PFEM
(2008-12)
Article
Accés obertThe paper aims to introduce new fluid–structure interaction (FSI) tests to compare experimental results with numerical ones. The examples have been chosen for a particular case for which experimental results are not much ... -
FIC/FEM formulation with matrix stabilizing terms for incompressible flows at low and high Reynolds numbers
(2006-09)
Article
Accés obertWe present a general formulation for incompressible fluid flow analysis using the finite element method. The necessary stabilization for dealing with convective effects and the incompressibility condition are introduced ... -
Nodally exact Ritz discretizations of 1D diffusion–absorption and Helmholtz equations by variational FIC and modified equation methods
(2007-01)
Article
Accés obertThis article presents the first application of the Finite Calculus (FIC) in a Ritz-FEM variational framework. FIC provides a steplength parametrization of mesh dimensions, which is used to modify the shape functions. This ... -
Simulation of flows with violent free surface motion and moving objects using unstructured grids
(2007-03)
Article
Accés obertA volume of fluid (VOF) technique has been developed and coupled with an incompressible Euler/Navier–Stokes solver operating on adaptive, unstructured grids to simulate the interactions of extreme waves and three-dimensional ... -
Multiscale analysis using a coupled discrete/finite element model
(Techno press, 2008-03)
Article
Accés restringit per política de l'editorialThe present paper presents multiscale modelling via coupling of the discrete and finite element methods. Theoretical formulation of the discrete element method using spherical or cylindrical particles has been briefly ...
