Description
Summary:The shear buckling analysis of laminated spherical shells with multiple cutouts is studied using the present mathematical model. In the present mathematical model, a transverse shear stresses have been varied parabolically across the thickness. The zero transverse shear stress conditions are introduced at the top and bottom of the shell without using a shear correction factor. Further, the cross curvature effect in spherical shells is included via strain relations. In this proposed mathematical model, the unknown parameters are required only at the reference plane. In this paper, a C0 continuity nine noded curved isoparametric element has been considered. Based on the proposed mathematical model, a computer code has been written to find out many new results for the variation in cutouts, boundary conditions, curvature and lamination schemes etc
