Abstract: An analytical model is presented to predict the nonlinear response of a double-wall sandwich cylindrical shell system subjected to random excitation. Nonlinear spring-dashpot models are integrated into the system to ...

Abstract: A numerical study of the use of electrorheological (ER) fluids and piezoelectric (PZT) actuators to control random vibrations of stiffened composite panels is presented. Active control of stiffness ...
