Abstract

This paper concerns the dynamic response of partially delaminated composite laminates impacted by a rigid ball. Nine-node isoparametric elements including the influence of shear deformation were used in the finite element analysis. In order to evaluate the contact force between the impactor and the laminate, the Hertzian contact law was adopted. The Newmark algorithm was employed to solve the motion of the impactor. To deal with the dynamic contact problem between two delaminated layers effectively, a Lagrange multiplier technique incorporated with a special time integration algorithm was presented to overcome the deficiency of the classical Lagrange multiplier method. The numerical results give much information of impact phenomena of delaminated composite laminates.
