A Two-Objective Optimization Approach to Vibration Reduction in Smart Angle-ply Composite Plate

In Current paper, the use of a two-objective optimization approach for vibration reduction in smart angle-ply composite plates is investigated. Power consumption and vertical displacement optimization of angle-ply composite plates subject to a step load are carried out by piezoelectric patches using the modified two-objective Artificial Bee Colony (ABC) algorithm. The voltages of patches, plate length/width ratios, ply angles, plate thickness/length ratios, number of layers and edge conditions are chosen as design variables. The formulation is based on the classical laminated plate theory (CLPT) and Hamilton's principle. The performance of the modified ABC approach is compared with the PSO algorithm and shows the good efficiency of the new ABC approach.
