Abstract

This paper investigates the low velocity oblique impact responses of delaminated torsion stiff composite pretwisted shallow conical shells. An eight-node isoparametric quadratic plate bending element is employed in the finite element formulation incorporating rotary inertia and the effects of transverse shear deformation based on Mindlin's theory. The modified Hertzian contact law is employed to evaluate the impact parameters, and the time-dependent equations are solved using Newmark's time integration scheme. Parametric studies are carried out to investigate the effects of triggering parameters such as twist angle, and the oblique angle when subjected to low velocity impact by a solid sphere at the centre.
