A minimum weight FEM formulation for Structural Topological Optimization with local stress constraints
(2005)
Since Bendsoe and Kikuchi proposed the basic concepts in 1988, most of topology structural optimization
results have been obtained so far by means of a maximum stiffness (minimum strain energy, minimum
compliance) approach. ...
A 2D numerical model for the transport of pollutants. The influence of Boundary Conditions
(Utah State University Extension, 1999)
[Abstract] The pollutants transport phenomena in a 2D unsteady free surface flow has been studied. The weighted residual method has been used for the integration of the transport equations, appying the Galerkin formulation ...
High order shape design sensitivity: an unified approach
(Centro Internacional de Métodos Numéricos en Ingeniería, 1998)
[Abstract] Three basic analytical approaches have been proposed for the calculation
of sensitivity derivatives in shape optimization problems. The first approach is based
on differentiation of the discretized equations. ...
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 ...
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 ...
IGA-based topology optimization in the design of stress-constrained compliant mechanisms
(Springer, 2023)
[Abstract:] Topology design of compliant mechanisms has gained wide popularity among the scientific community, and their use in the mechanical engineering field is being of upmost importance. In this paper, an isogeometric ...
Structural topology optimization with high spatial definition by using the overweight approach
(WIT Press, 2022)
[Abstract:] The first formulation of topology optimization was proposed in the 1980s. Since then, many contributions have been presented with the purpose of improving its efficiency and expanding its field of application. ...
