Fea Performance Comparisons Of Nnpb And Bb Refillable Bottles

Glass bottles fracture when the magnitude of the tensile stress, created from applied loads such as internal pressure, impact or vertical load, equals or exceeds the glass strength at any given point on the surface of the container. Based on this general relationship, two variables determine the overall performance of a bottle: The strength of the glass surface; and the magnitude of tensile stress created in the glass by various applied loads. By identifying the difference in surface strength based on trade conditions and manufacturing processes, strength criteria is established. This article provides an example - the performance of a 330ml refillable beer bottle design is evaluated and discussed.
