| Abstract: | A fifteen-variable quasi-conforming triangle element including coupling and transverse shear effect and two-nodes incompatible beam element are used for the buckling analysis of stiffened composite laminated shells in this paper.A variety of numerical examples are presented to demonstrate that this approach can well be applied to the irregular boundary and has the advantages of simplicity,efficiency and acceptable accuracy. |
