Abstract

The paper presented here proposes to verify the mechanical behavior of an optimized simply supported truss with 5 nodes and 6 bars, obtained from a genetic algorithm optimization using population size 450. For the purpose of developing this paper, it was used as reference an optimization already performed in a previous article and its results. In order to perform this ascertainment, we compared the structure's stress and displacement results to those found through the finite element software Abaqus® and an analytical analysis. The first consists of modeling and analyzing the optimized truss using Abaqus® software. This analysis has the objective of confirming the reference paper results through a software that has been used widely by finite element specialists. The second is based on a Matlab® application to develop the stiffness matrix of the optimized structure. The applications ratified that the results obtained in the reference paper are consistent.
