| Description |
The impact response and the impact-induced damage in curved composite laminates
subjected to transverse impact by a metallic impactor are studied using three-dimensional
non-linear finite element formulation. A layered version of isoparametric eight-noded
hexahedral element with incompatible modes is developed which incorporates geometrical
non-linearity based on total Langragian approach. The non-linearity of both strain
displacement relation and contact loading are simultaneously solved using Newton-Raphson
incremental–iterative method. Impact-induced damages (matrix cracking and delamination)
are predicted using appropriate three-dimensional stress-based failure criteria. Example
problems of graphite/epoxy laminated cylindrical shells are considered and the influence of
geometrical non-linear effect on both impact response and resulting damages is demonstrated.
Effects of different parameters such as impactor velocity, shell curvature, laminate dimension
and fibre orientation of plies are also investigated
