Optimización de secciones ortótropas sometidas a torsión mediante el método de los elementos de contorno

== Abstract ==

The aim of this paper is the solution of the shape optimization problem for simply and multiply-connected orthotropic sections under Saint-Venant torsion by using the Boundary Element Method. The objective function is the area of the section, while the only constraint corresponds to a given torsional stiffness. The nonlinear optimization algorithm is also discussed, so they are the different criteria used to get a consistent and automatic boundary redefinition looking for a ininimum number of iterations in the optimization process. Finally, a brief description of the program and several examples are also included.
