Abstract

Aluminum metal beverage container is used in packaging foods and chemical industries because of its superior hold, formability, corrosion resistance and join ability. The 80 percent of the container cost is material and aluminum metal is expansive one. The beverage container industry is struggling for potential saving from weight reduction in each container, while meeting the three structural performance standards which have been established to assess the adequacy of the container design. These are axial column load, drop resistance and internal pressure. This paper relates to the internal pressure standard which states that container must withstand at least 90-100PSI or more internal pressure without buckling (reversal of dome). The purpose of this research is to minimize the weight of an aluminum beverage container as well as fulfilling the entire remaining design parameters such as applied loads, maximum stresses at critical locations and keeping in view all other constraints. A number of alternative solutions are analyzed at a very low cost, using simple FE analysis. Based on these results, promising designs are further analyzed using more complex but accurate FE techniques. A series of different designs are developed, analyzed and an optimum design is considered. The linear analysis is done using Cosmos Works, Solid Works and ANSYS. The results are validated using available experimental and numerical data.
