A. Tabiei, BUCKLING OF MODERATELY THICK COMPOSITE CYLINDRICAL-SHELLS UNDER DESTABILIZING LOADS, Journal of thermoplastic composite materials, 8(4), 1995, pp. 365-374
The instability of perfect, laminated, circular cylindrical shells wit
h fixed ends under the action of uniform axial compression, lateral pr
essure, and torsion is investigated. The analysis is based on nonlinea
r kinematic relations where the effect of transverse shear deformation
is taken into account. Three theories (higher order shear deformation
theory, first-order shear deformation theory, and classical) are comp
ared to determine their range or applicability in predicting critical
conditions for moderately thick cylindrical shells under the action of
various loads. Also, the effects of stacking sequence, radius-to-thic
kness ratio, and length-to-radius ratio are assessed. The results obta
ined indicate that the first-order shear deformation theory with a pro
per shear correction factor is a good candidate for the analysis of mo
derately thick laminated cylindrical shells.
