An Analysis of Postbuckling Behavior of Composite Laminated Curved Plates under Uniaxial Compression with Initial Imperfections

Buckling Behavior of Composite Plates with a Pre-central Circular Delamination Defect under in-Plane Uniaxial Compression

Delamination is one of the most common failure modes in composite structures. In the case of in-plane compressional loading, delamination of a layered flat structure can cause a local buckling in delaminated area which subsequently affects the overall stiffness of the initial structure. This leads to an early failure of the overall structure. Moreover, with an increase in load, the delaminated ...

Buckling Analysis of Rectangular Laminated Composite Plates With An Edge Delamination Under Compressive Load

The buckling analysis of rectangular laminated composite plates with an edge delamination under in-plane compressive loading is performed using the finite element method. Such a plate may be considered as a simplified model of stiffener plates of a stiffened panel. The buckling load and buckling mode are obtained by solving an eigenproblem. In an unconstrained analysis, physically inadmissible ...

Buckling and Postbuckling Behavior of Laminated Composite Plates With a Cutout

Bending Analysis of Laminated Composite Plates with Arbitrary Boundary Conditions

It is well known that for laminated composite plates a Levy-type solution exists only for cross-ply and antisymmetric angle-ply laminates. Numerous investigators have used the Levy method to solve the governing equations of various equivalent single-layer plate theories. It is the intension of the present study to introduce a method for analytical solutions of laminated composite plates with ar...

Initial Postbuckling Behavior of Shear Deformable Symmetrically Laminated Beams

Abstract-Results for the initial postbuckling behavior of laminated beams are presented. Shear deformation effects are incorporated by relaxing certain assumptions of thin beam/plate theory. The analysis used is in the spirit of Koiter [Doctoral thesis, Delft, Amsterdam, English translation AFFDL-TR-70-25, (1970)], who developed asymptotic expressions for the potential energy in the neighborhoo...
