Buckling behavior of the multiple delaminated composite plates under shear and axial compression

摘要

In the paper, a methodology to evaluate the influence of the double delaminations on the buckling and postbuckling behavior of the composite plates under shear and compression loading, used in ship hull structure, is presented. The parametric calculus was done for various positions of delaminations and seven values of loading ratios. The numerical and experimental tests on the delaminated plates are presented. Composite plates containing a multiple number of delaminations are analyzed with respect to combined boundary shear and axial compression buckling. Finally, the graphical results for one position of the delamination through the thickness and two cases of position of delaminations in the case of double delaminated plate and seven values of loading ratio are presented.
