Multiobjective optimization for vibration reduction in composite plate structures using constrained layer damping
Abstract eng: The optimal design of laminated composite panels with Constrained Layer Damping (CLD) treatments is addressed in this paper. The objectives are simultaneously to minimize weight and maximize modal damping. The design variables are the number and position of CLD patch treatments on the surface of the laminated plate. The problem is solved using the Direct MultiSearch (DMS) solver for multiobjective optimization problems which does not use any derivatives of the objective functions. A finite element model for sandwich plates with viscoelastic core and anisotropic laminated face layers is adapted to model the plate with the CLD treatments. Trade-off Pareto optimal fronts and the respective treatment configurations are obtained and the results are analyzed and discussed.
