Optimización de Forma de Placas Cargadas en su Plano Mediante Algoritmos Genéticos y Elementos de Contorno

Abstract

In this work,the shape optimization problem for 2-D elastic isotropic solids is formulated. The objetive function is the minimum weight design with limiting values of maximum stresses.
A Genetic Algorithm to optimize boundary element models is discussed. The models are represented by a bit string (chromosome), so we start with a chromosome population created by random, then it is evaluated and the three trans
formation operators: selection, cross and mutation are applied to get a new population and so on, until the best chromosome is reached.
Finally several examples and their conclusions are also presented.
