Description
A wrinkling analysis is presented for cylindrical sandwich shells subjected to torsion. The core of sandwich shells is assumed to be homogeneous and anti-plane orthotropic material, while the two facings are of equal thickness and have own bending stiffnesses. As the whole bending stiffness of sandwich shells is taken in the analysis, so buckling of the analysis unifies the wrinkling and the over-all buckling. A length of cylindrical shells is so long that the boundary conditions do not affect to the wrinkling loads. If a helical buckling deformation is assumed, then stresses in the core can be expressed in a matrix form in terms of facing displacements. Finally a DONNEL's type of equilibrium of the facings is reduced to algebraic eigenvalue equations.<BR>The numerical results obtained by this method were compared with the solutions of over-all buckling analysis by MARCH and KUENZI, and the fact, that the wrinkling stresses are lower than the over-all buckling stresses for cylindrical sandwich shells subjected to torsion when the core is relatively thick, is revealed.
