Lateral Impact of Composite Cylinders

Source

An analytical study was conducted to explore and understand the mechanics of the lateral low-velocity impact of composite cylinders by a heavy mass. Two simple models are presented, which when compared with the experimental data demonstrate that the fundamental features of the impact event are represented. Although the results are preliminary, a failure model based on linear laminated shell theory and linear fracture mechanics gave a reasonable representation of the observed impact damage. A nonlinear ring model gave good insight into the physics of the impact event in the presence of delaminations and the resulting nonlinear effects.
