Abstract:
This study presents the bending analysis of laminated conical panels under transverse compression with various boundary conditions. Equations was derived using first order shear deformation theory (FSDT) and solved using generalized differential quadrature (GDQ) method. Using this method results in the capability of studying any combinations of boundary conditions on four edges of the panel. Results are compared and validated with the results available in the literature. Effect of boundary conditions, panel length, semi-vertex angle and subtended angle on deflection of the panel was investigated.The buckling analysis of cross-ply laminated conical shell panels with simply supported boundary conditions at all edges and subjected to axial compression is studied. Equations were derived using classical shell theory (CST) and solved using generalized differential quadrature (GDQ) method. The accuracy of results is compared with the other papers and the effects of subtended and semi-vertex angles and the length, thickness and radius of the panel on buckling load are also investigated
