Description	The possibility to accurately analyse the buckling behaviour of delaminated plates utilising simplified circular or elliptic representations of delaminations with irregular shapes was investigated. The smallest enclosing circle and smallest enclosing ellipse algorithms were used to obtain the simplified representations of impact induced delaminations. Finite element postbuckling simulations of compressed plates were than performed and the responses of the plates with irregular delaminations and corresponding circular and elliptic delaminations were compared in terms of buckling loads and maximum energy release rate values found along the delamination boundaries. It was found, that utilisation of the circular representation of the true shape of delaminations could lead to highly inaccurate results and therefore elliptic representation should be used instead. However, for an accurate analyses of buckling and postbuckling behaviour of delaminated structures it seems to be inevitable to use as precise The possibility to accurately analyse the buckling behaviour of delaminated plates utilising simplified circular or elliptic representations of delaminations with irregular shapes was investigated.
