Buckling Analysis of the Composite Plates with Delamination and Growth of Delamination with CZM Method

چکیده مقاله

In this paper, a study of the influence of elliptical delamination and growth of delamination on buckling load behavior made of composite material is treated. Delamination and growth of delamination has been developed by using the surface-to-surface contact option in Finite element method software. So, the damaged and the undamaged part of the structure have been represented by well-known finite elements. The numerical results are compared with the experiments made on the square plates. By using of the results of elliptical delamination simulation in delaminated zone and buckling load behavior specification to the influence of the position and the ellipse’s diameters ratio, to study has been investigated on the growth of delamination by cohesive elements technique.
