An analytic method for interlaminar stress in a laminated cylindrical shell

The present article studies the problem of interlaminar stress in a cross-ply laminated cylindrical shell under radial pressure. The elasticity solution of the problem can be obtained by making use of orthotropic elastic theory. At first, an analytic solution for a separate cross-ply cylindrical shell is woked out by means of orthotropic elastic theory. Then, boundary conditions at internal-external surfaces and continuity conditions at the interface are used to determine the unknown constants involved in this solution. Thus, an exact solution for interlaminar stresses in a laminated cylindrical shell is obtained. Finally, the distributions of the interlaminar stresses in laminated shells with various stacking sequences under radial pressure are given and the length of the bending boundary layer-giving effect on interlaminar stresses in a laminated cylindrical shell is discussed.
