Topology optimization has exhibited an exceptional capability of improving structural design.
However, several typical topology optimization algorithms are finite element (FE) based …

This paper details the development of the fixed grid FEA (FGFEA) method to the solution of
eigenvalue (natural frequency and buckling) problems, using a 4 node 20 degree of …

Topological optimization can be considered as one of the most general types of structural
optimization. Between all known topological optimization techniques, the Evolutionary …

El objetivo de la optimización de estructuras es obtener un diseño, es decir, un conjunto de
