Analysis of enhanced modal damping ratio in porous materials using an acoustic-structure interaction model
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 appro...
