Abstract :
In the present study a shear deformable shell element is developed based on Reissnerʹs hypothesis for the analysis of smart laminated composite shells. The electric field is defined in the curvilinear co-ordinate system. The mathematics of arbitrary shell geometry is amenable to the flexible mapping characteristic of the finite element formulation developed in the present work. Lameʹs parameters and the radii of curvature are generated within the model. An IMSC based LQR control methodology is adopted for the active vibration control of laminated spherical shell with different fibre orientation and varying radius of curvature. Results are presented and are discussed.
