A boundary element formulation for the substation grounding design
(Elsevier, 1999)
[Abstract] A Boundary Element approach for the numerical computation of substation grounding systems is presented. In this general formulation, several widespread intuitive methods (such as Average Potential
Method) can ...
A numerical formulation for grounding analysis in stratified soils
(IEEE Power Engineering Society, 2002)
[Abstract] The design of safe grounding systems in electrical installations is essential to assure the security of the persons, the protection of the equipment and the continuity of the power supply. In order to achieve ...
Topology optimization of structures: a minimum weight approach with stress constraints
(Elsevier, 2004)
Sizing and shape structural optimization problems are normally stated in terms of
a minimum weight approach with constraints that limit the maximum allowable
stresses and displacements.
However, topology structural ...
Finite volume solvers and moving least-squares approximations for the compressible Navier-Stokes equations on unstructured grids
(Elsevier, 2005)
[Abstract] This paper introduces the use of Moving Least-Squares (MLS) approximations for
the development of high order upwind schemes on unstructured grids, applied to
the numerical solution of the compressible Navier-Stokes ...
On the Galerkin formulation of the smoothed particle hydrodynamics method
(John Wiley and Sons, 2004)
[Abstract] In this paper, we propose a Galerkin-based smoothed particle hydrodynamics (SPH) formulation with
moving least-squares meshless approximation, applied to free surface flows. The Galerkin scheme
provides a clear ...
A Mathematical Model to Evaluate the Impact of the Maintenance Strategy on the Service Life of Flexible Pavements
(Hindawi, 2019)
[Abstract] The structural failure of a flexible pavement occurs when the accumulated fatigue damage produced by all the vehicles that have passed over each section exceeds a certain threshold. For this reason, the service ...
High Order Shape Design Sensitivity: A Unified Approach
(Elsevier, 2000)
[Abstract] Three basic analytical approaches have been proposed for the calculation of sen-
sitivity derivatives in shape optimization problems. The first approach is based on
differentiation of the discretized equations ...
Why do computer methods for grounding analysis produce anomalous results?
(IEEE Power Engineering Society, 2003)
[Abstract] Grounding systems are designed to guarantee personal security, protection of equipments and continuity of power
supply. Hence, engineers must compute the equivalent resistance of the system and the potential ...
Improved δ-SPH Scheme With Automatic and Adaptive Numerical Dissipation
(MDPI, 2020)
[Abstract] In this work we present a δ-Smoothed Particle Hydrodynamics (SPH) scheme for weakly compressible flows with automatic adaptive numerical dissipation. The resulting scheme is a meshless self-adaptive method, in ...
Topology optimization of structures considering minimum weight and stress constraints by using the Overweight Approach
(Elsevier, 2022)
[Abstract:] In this paper, a new method for structural topology optimization considering minimum weight and local stress constraints is proposed. For this purpose, the Overweight Approach, an improvement of the so-called ...
