Optimal Design of Smart Skin Structures for Thermo-Mechanical Buckling and Vibration using a Genetic Algorithm
Smart skin was analyzed for buckling and vibration. Thermal effects were taken into consideration, because the temperature rise may induce buckling or resonance on the skin. The model was a multi-layer sandwich structure composed of carbon/epoxy, glass/epoxy and a dielectric polymer. A numerical mod...

Summary: | Smart skin was analyzed for buckling and vibration. Thermal effects were taken into consideration, because the temperature rise may induce buckling or resonance on the skin. The model was a multi-layer sandwich structure composed of carbon/epoxy, glass/epoxy and a dielectric polymer. A numerical model was used to find design data from various parameters such as the aspect ratio, thickness of core, ply-angle and area ratio. In addition, each variable's effect on the model was studied. The results were compared to a case in which the thermal effect was not considered. The formulation of the structural model was based on the first-order shear deformation plate theory (FSDT) and numerical results were obtained by finite element method. Finally, a genetic algorithm was used to maximize the critical temperature and natural frequency of the structure. |
