Postbuckling responses of delaminated composite struts are semi‐analytically modelled. The model used allows to describe the postbuckling behaviour beyond the state where delamination growth is initiated. In the current work, a multi‐layered composite strut of differently stacked transversally isotropic unidirectional layers is investigated. A pre‐existing delamination is assigned in between two layers. By using only four generalized coordinates postbuckling responses incorporating delamination growth are determined. © 2016 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
