Abstract

The present study reports finite element analysis of hyperbolic paraboloid composite shells for static analysis under uniform pressure to examine the maximum stresses and deflections. The matrix used in the present study is Epoxy resin reinforced with E-glass fiber. Parameter used for the analysis is rise-to-span-ratio (c/a). The ratio used for the study varies from 0 to 0.5 with linear increment of 0.05. Thickness of composite layer is kept equal in the shell. Eight-nodded iso-parametric shell element with five degrees of freedom on each node is used for the present study. Boundary conditions with all sides clamped, all sides simply supported and alternate sides simply supported and clamped are applied with cross-ply and angle-ply laminations.
