The aim of this paper is to discuss different finite element models of laminated composite plates with delaminations using the commercial software Abaqus CAE. Three-dimensional (solid), as well as two-dimensional (shell) models in Abaqus CAE, are considered. For comparison, the previously derived and validated numerical model of both intact and delaminated composite plates, based on the Generalized Layerwise Plate Theory of Reddy, is used. Influences of the finite element types and the mesh density on the free vibration response are analysed. Excellent agreement is achieved using the shell model in Abaqus CAE, while the limitations of solid models are noted.
