Diseño basado en confiabilidad de paneles navales fabricados en compuestos reforzados con fibras utilizando algoritmos evolutivos y mecánica estructural estocástica

Resumen

A methodology based on evolutionary algorithms and stochastic structural mechanics for the design of high-reliability naval multilayer composite structural panels, is presented.

Mechanical response of structural panels was modeled using the Multilayer Classical Plate Theory and Finite Element Method.

Sea wave loads were modeled as stochastic dynamic loads using the Simulation Based Reliability Analysis approach.

The structural reliability of the panel, as function of the composite ply’s fiber direction, was considered as a design variable.

In order to maximize the structural reliability, an optimization methodology based on stochastic algorithms, was proposed.
