Abstract

Analytical and numerical formulations and simulations are carried out in order to conduct sensitivity studies of physical parameters affecting acoustic and motion control by viscoelastic piezoelectric and material damping. Numerical simulations in terms of critical parameters, such as relaxation functions of the structure and piezoelectric devices, aerodynamic coefficients, Mach number, are carried out to evaluate system responses, sensing and structural control.
