摘要：

The dynamic instability analysis of parametrically excited truncated conical shells subjected to periodic in-plane loads is investigated using CO two-noded shear flexible shell element. The present model accounts for in-plane and rotary inertia effects. The boundaries of the principal instability region obtained here are conveniently represented in the non-dimensional excitation frequency-non-dimensional load amplitude plane. The influences of various parameters such as cone orthotropicity, cone angle, ply-angle and elastic edge restraint on dynamic stability are brought out.
