AIP Advances, 2014 The aim of this paper is to investigate the enhancement of the damping ratio of a structure with embedded microbeam resonators in air-filled internal cavities. In this context, we discuss theoretical aspects in the framework of the effective modal damping ratio (MDR) and derive an approximate relation expressing how an increased damping due to the ...

Modal damping ratio reliability-based topology optimization of composite cellular structures
Abstract Reducing vibrations in the structure can be performed by damping cellular materials. Maximizing the modal damping ratio (MDR) as a physical characteristic of these materials can serve as an effective strategy, which can be applied through deterministic topology optimization (TO).
