摘要：
The dynamic instability analysis of truncated conical shell subjected to periodic in-plane load is investigated using C degrees 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. (C) 1999 Elsevier Science Ltd.
