Nonlinear Dynamic Analysis of Series Cushioning System Made with Expanded Polyethylene and Corrugated Paperboard

Based on the constitutive models of expanded polyethylene (EPE) and C-flute corrugated paperboard (CCP), the drop impact model for expanded polyethylene in series with CCP was established to consider the effect of cushioning action for CCP box. A numerical procedure was adopted for the optimization of the product packaging system by considering the action of the corrugated paperboard box. Then the optimal results were obtained and compared without considering the effect of CCP. Finally, the calculation reliability was proved by the comparison between calculated results and experimental data.
