Effect of Internal Gas Pressure on the Compression Strength of Beverage Cans and Plastic Bottles
This study investigated the compression strength of various sized polyethylene terephthalate (PET) bottles and steel and aluminum two-piece cans. Compression tests were performed on both empty and filled containers under pressure. A stress analysis is developed to provide a simple prediction formula. The predictions are shown to be in fair agreement with actual values obtained from the compression tests. The results show that internal pressure can increase the compression strength of a beverage package by as much as three times. Erratum to this paper appears in 21(4).
