A minimum weight with stress constraints FEM approach for topology structural optimization problems
[Abstract] 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 ...
Desarrollo de una formulación basada en los métodos multiescala para la resolución de problemas de transporte convectivo-difusivos
[Resumen] La resolución de la ecuación de convección-difusión mediante el Método de los Elementos Finitos con ponderación convencional tipo Galerkin presenta numerosas inestabilidades cuando la velocidad del fluido es ...
SPH approaches for free surface flow for engineering applications
[Abstract] In this paper, we study different SPH formulations proposed to solve free surface problems. We center our attention in the corrections added to the SPH method in order to increase its accuracy and to improve its ...
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 ...
A general numerical model for grounding analysis in layered soils
[Abstract] Safety of persons, protection and equipment and continuity of power supply are the main objectives of the grounding system of a large electrical installation. For its accurate design, it is essential to determine ...
