heal.abstract	The purpose of this work is to investigate the effect of delaminations on the buckling behaviour of a marine composite hull. This is done by using the Finite Element Method to model delaminations and calculate the buckling strength of a typical marine composite panel. The parametric study is based on a marine panel clamped along all its edges and loaded in compression. The delamination was assumed to have an elliptic shape and the parameters investigated in the analysis were its shape, magnitude and location. The total number of cases investigated is 45. The eigenvalue buckling analyses led in many cases in inadmissible buckling modeshapes. A procedure for eliminating these inadmissible modeshapes in the nonlinear analyses is described in the paper. The final results indicated that the greatest effect comes from delaminations which are closer to the laminate surface, are closer to the circular shape and have the largest magnitude. © 2009 Taylor & Francis Group, London.	en
