The modal frequencies and loss factors of a simply supported beam with an enhanced active constrained layer (EACL) damping treatment are derived by the extended Hamilton principle and Rayleigh-Ritz method while open-and closed-loop control (displacement and velocity feedback) systems are considered.

This work deals with the active vibration control of beams with smart constrained layer damping (SCLD) treatment. SCLD design consists of viscoelastic shear layer sandwiched between two layers of piezoelectric sensors and actuator. This composite SCLD when bonded to a vibrating structure acts as a s
The "nite element method (FEM) is combined with the Golla}Hughes}McTavish (GHM) model of viscoelastic materials (VEM) to model a cantilever beam with active constrained layer damping treatments. This approach avoids time-consuming iteration in solving modal frequencies, modal damping ratios and resp
