Abstract
Introduction of laminated composites in the weight sensitive branches of engineering has opened a new avenue of application for their high specific stiffness and good weathering resistance. In spite of these advantages laminated composites are vulnerable to sudden impact due to their low transverse shear capacity than other conventional construction materials like steel and concrete. In most of the situations these impacts are oblique. In the cases of oblique impact due sliding of the impactor friction generates. Present paper aims to carry out dynamic analysis of composite hypar shell roof for clamped boundary condition under oblique impact stricken at different oblique angles. Effect of dry friction between the impactor and shell surface is considered in the present formulation. Time histories of contact force and deflection are presented graphically and critically analysed to give some conclusion of engineering significance at the end.
