Abstract: In this paper, the buckling analysis of laminates with an embedded delaminationhas been conducted by employing the finite element method based on the Mindlin plate theory.To avoid the overlap between two delaminated layers in the buckling mode, an effective solutionmethod has been put forward to deal with the contact problem in the buckling analysis. In thismethod, an iterative updating process incorporating the first-order sensitivity gnalysis and thequadratic programming technique has been proposed to com...
