Abstract
This work presents an evolutionary optimization method for single cell thin-walled composite beams based on a phenomenological failure criterion. A case study of a wing spar is described. The structural mechanical modeling developed considers axial warping and full anisotropic effects and does not include the influence of transversal shear loads. Using a genetic algorithm toolbox previously developed, some structural parameters are evaluated to reach optimal circular cross-section spar designs. Dimensional and structural project constraints are considered aiming a multi-objective fitness function that minimizes weight and maximizes the laminate stiffness. Comparisons between previously obtained results for the same structure are carried out.
