This paper is studying local buckling of delaminated cylindrical shells under distributed normal load, where it often causes delamination propagation and structural collapse. The governing differential equations are derived depending on variational principle, the corresponding end conditions and continuity conditions are applied. The associated energy release rate with the delamination is obtained and generalized differential quadrature method is used to solve nonlinear governing equations. Effects of delamination sizes and depths on delamination propagation are discussed.
