| Description |
The impact response and impact-induced damage in curved composite laminates subjected to
transverse impact by a metallic impactor are studied using a non-linear finite element shell formulation.
An eight-noded isoparametric quadrilateral shell element incorporating non-linearity due to large
deflection is developed based on the total Langragian approach. The non-linearity of both strain
displacement relation and contact loading are simultaneously solved iteratively using a modified Newton-
Raphson method. Impact-induced damage in the form of matrix cracking is predicted using an
appropriate three-dimensional stress-based failure criterion. In order to take account of degradation of
material due to damage during the impact, the stiffness matrix of the failed region of the laminate is
appropriately reduced as the solution progresses. Example problems of graphite/epoxy cylindrically
curved laminates are considered and the influence of a geometrical non-linear effect on the impact
response and impact-induced damage is demonstrated. Effects of important parameters such as shell
curvature and fibre orientation of plies are also investigated. The effect of material degradation on the
impact response and resulting damage are also discussed.
