ON THE EFFECTS OF FIBER ORIENTATION AND NONHOMOGENEITY ON BUCKLING AND POSTBUCKLING EQUILIBRIUM BEHAVIOR OF FIBER-REINFORCED CYLINDRICAL SHELLS UNDER UNIFORM AXIAL COMPRESSION.
Abstract
A theoretical analysis of the buckling and postbuckling equilibrium behavior of a fiber reinforced cylindrical shell under uniform axial compression is presented. The von Karman-Donnell large-displacement equations and the principle of stationary potential energy is applied to study the postbuckling behavior. The results are given for various fiber orientations in the three-layer shell consisting of either glass-epoxy or boron-epoxy composites. Both the cases, where the stiffness coupling matrix (D) is not equal to zero, and where the matrix (D) is set equal to zero are considered. The latter case gives higher values of classical buckling load and postbuckling loads. The fiber orientation giving the greatest value of classical buckling load is found. (Author)
