Abstract:The smart composite material possessed of self-detecting damage function is a multi-sensor architecture.It has been of great practical value and is worth to researching further to optimize sensors' locations and number for the smart composite material.An effective impact damage detection procedure is established by using a neural network approach.A genetic algorithm combined with neural networks is used to determine the optimum three-sensor positions for damage detection on a composite panel.The result is validated against an exhaustive search.The method presented is generic and can be effectively used in similar more sensors' placement problems.
Keywords:Neural networks Genetic algorithms Damage detection Optimal sensor placement
