Modelling Drop Impact and Fracture of Fluid-Filled Plastic Containers
Proceedings of the 15th European Conference on Fracture, (2004)
Abstract
Drop impact resistance of fluid-filled plastic containers is of considerable concern to plasticsand containers manufacturers as well as distribution industries utilising containers fortransportation of various liquids. This is due to potential failure of the containers followingthe drop impact and subsequent spillage of the transported liquid. In this work, a combinedexperimental-numerical study of the problem is presented. Experimental investigation wasconducted on 1-litre cylindrical bottles made from polyethylene. Bottles were dropped from agiven height onto a concrete floor, and pressure in the contained fluid was recorded duringthe experiment using pressure transducers. Numerical analysis was performed using FiniteVolume based fluid-structure-fracture procedure. Here, Cohesive Zone methodology isintroduced into the standard two-system solid-fluid coupling procedure to simulate andpredict the failure process. It is shown that numerically predicted pressure and strain historieshave good resemblance with experimental results.
