Abstract
ABSTRACT A rigorous multi-objective optimization procedure, is developed to address the integrated structures/control design ofcomposite plates with surface bonded segmented active constrained layer (ACL) damping treatment. The Kresselmeier-Steinhauser function approach is used to formulate this multidisciplinary problem. The goal is to control vibration withoutincorporating a weight penalty. Objective functions and constraints include damping ratios, structural weight and naturalfrequencies. Design variables include the ply stacking sequence, dimensions and placement of segmented ACL. The optimaldesigns show improved plate vibratory characteristics and reduced structural weight. The results of the multi-objectiveoptimization problem are compared to those of a single objective optimization with vibration control as the objective.Results establish the necessity for developing the integrated structures/controls optimization procedure.Keywords: integrated design, optimization, smart composites, segmented active constrained layer, hybrid displacement field
