Modeling and evaluation of rectangular hole effect on nonlinear behavior of imperfect composite plates by an effective simulation technique
S.A.M. Ghannadpour and M. Mehrparvar

 
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
