Abstract
In the present paper static analysis of laminated composite conoidal shells in the presence of delamination is investigated. Simply supported conoidal shells are subjected to uniform loading. Finite element method using eight-noded curved quadratic isoparametric shell element with 5 degrees of freedom (d.o.f) per node is used in the present research work. To ensure compatibility between deflection and equilibrium of moments and forces, an advance feature known as MPC algorithm is integrated in the present model. This generates an unsymmetrical stiffness matrix. The exactness of present model is verified by comparing with the results of previous researchers’ works. Studies are done by varying the lamination schemes, extent of delamination and aspect ratio for composite conoidal shells. Boundary condition is kept as simply supported for all the shells considered in the present study.
