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 ...
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 ...
