摘要：
A higher-order shear deformation theory has been employed for evaluating accurately the transverse shear effects in delamination buckling of cylindrical shells under axial compression. The governing differential equations of the present theory are obtained by applying the principle of the stationary value of the total potential. The Rayleigh-Ritz method is used to solve the equations by assuming a double Fourier expansion of the displacements with trigonometric coordinate functions. Numerical results for linear delamination buckling of axially compressed cylindrical shells with clamped ends are presented to validate the theory. Comparisons are made with the classical laminate theory and first-order theory results.
