DYNAMIC STABILITY OF CROSS-PLY LAMINATED COMPOSITE CYLINDRICAL-SHELLS

The dynamic stability of thin, laminated cylindrical shells under comb ined static and periodic axial forces is studied using Love's classica l theory of thin shells. A normal-mode expansion of the equations of m otion yields a system of Mathieu-Hill equations. Bolotin's method is t hen employed to obtain the dynamic instability regions. The present st udy examines the dynamic stability of antisymmetric cross-ply circular , cylindrical shells of different lamination schemes. The effect of th e magnitude of the axial load on the instability regions is also exami ned. (C) 1998 Elsevier Science Ltd. All rights reserved.
