Numerical Modelling of Carbon/Epoxy Laminated Plate Impact Damage

Abstract. Numerical simulation of static indentation and lateral impact tests of carbon/epoxy laminated composite plates, using ADINA finite element system is presented. The geometry, loading and boundary conditions used in simulation were determined by the drop test Rosand system that will be used to compare numerical results. Unidirectional and several 0/90 ply orientations stacking sequences carbon/epoxy plates were used in order to study the influence of thickness and ply orientation on the deformation and failure of the plates. Linear and nonlinear static response analyses were considered in the simulations of displacements and the extent and nature of damage. In the development of these studies, combined use of finite element analysis and impact testing is necessary to assess the damage tolerance of composite components. Afterwards, by parametric studies, it will be possible to study in a systematic way the effects of thickness, shape, ply orientations and duration of impact on deformation and failure of the plates.
