Rapid heating-induced vibration of composite magnetostrictive shells

ABSTRACT

The generalized differential quadrature method is used to obtain the computational results of three-layer cross-ply composite magnetostrictive shells under sudden uniform heat-induced vibration. In the thermal vibration analyses of a laminated magnetostrictive shell, the sudden uniform heat input over its inner surface only and temperature load is linear of axial coordinate. The shell with velocity feedback control loop and with suitable gain value can reduce the amplitudes of displacement and stress to smaller values, respectively, almost to a 0 value due to the control law contribution of the magnetostrictive layer.
