Abstract
In the present study, geometrically nonlinear behavior of relatively thick composite laminates containing square and rectangular cutouts with or without initial geometric imperfection has been investigated. The effects of cutout size, shape and presence of initial geometric imperfection for plates under uniaxial in-plane compressive load are studied. The structural model is based on the first-order shear deformation theory and Von-Karman
