STATIC BUCKLING OF MODERATELY THICK, ANISOTROPIC, LAMINATED AND SANDWICH CYLINDRICAL-SHELL PANELS

This paper deals with the development of the linearized equations governing the buckling behavior of moderately thick, anisotropic, laminated, and sandwich cylindrical shell panels faced with fiber-reinforced plastic under uniform shear and normal membrane forces. The formulation takes into account the transverse shear flexibility. Two approaches for the approximate solution of the elastic stability equations are developed. The first approach is an analytical approach of the Galerkin type and rests upon the principle of virtual work. The second is a finite-element displacement approach. Some numerical results are presented and compared with other results from the open literature. © 1990 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
