Abstract
The dynamic instability of laminated composite circular cylindrical sh ells subjected to periodic load is studied using a C degrees shear fle xible two-noded axisymmetric shell element. The formulation includes t he effects of inplane and rotary terms. The boundaries of the principa l instability regions are conveniently represented in the non-dimensio nal excitation frequency-non-dimensional load amplitude plane. The eff ects of various parameters such as ply-angle, thickness, aspect-ratio, axial and circumferential wave numbers on dynamic stability are broug ht out. (C) 1998 Elsevier Science Ltd.
