Shape optimization of two-dimensional body utilizing genetic algorithms

Abstract

The paper proposes a technology for shape optimization of two-dimensional body utilizing genetic algorithm. Main attention is focused on geometry of 2D body, i. e. search for optimal coordinates of body points. Direct analysis of 2D body – von Mises stress determination – is performed using original program based on finite element method. The set of design parameters contains the coordinates of body points in 2D space. The results of numerical experiments proved the proposed technology to be efficient tool for solution of 2D body shape optimization problem.
