Abstract(s)

The main purpose of this study was to optimize the fibers orientation in a composite specimen with the objective to minimize the displacement. This composite specimen can be used in aerospace or mechanical structures. The objective function was performed with static analysis by altering the fibers orientation in a finite element solid model, computed using the ANSYS program. A recent method for global optimization GLODS (Global and local optimization using direct search) was used for the optimization process. In the sequence, specimens were manufactured and experimental tested, in o order to validate the numerical results obtained.
