In the paper, a study of the influence of elliptical delamination on the changes in the buckling behaviour of ship deck plates made of composite materials is treated. An delamination model has been developed by using the surface-to-surface contact option, in licensed FEM code COSMOS/M. So, the damaged part of the structures and the undamaged part have been represented by well-known finite elements (layered shell elements). The numerical results are compared with the experiments made on the square plates. The influence of the position and the ellipse's diameters ratio of delaminated zone on the critical buckling force was investigated. (c) 2010 Elsevier B.V. All rights reserved.
