Introduce a formulation of loss factor to assess MDR(s) for classical and non-classical damping. Present extended MIST method for maximum modal damping ratio (MDR) of composite structures. Propose a multi-objective optimization method for simultaneous maximization of a set of MDRs. Develop a scheme for concurrent design optimization of host and VEM layers for maximizing MDR(s).
