AbstractThis study focuses on the computational modelling of an aerosol can by predicting the level of pop-up and burst pressure levels as the can is subjected to increased pressure loading, along with the determination to top load force causing can wall buckling. Numerical findings are assessed against European Packaging Standard and experimental trials for reliability of such a design. The challenge of the present study is the use of in situ data to mimic the can predictive behaviour within the Ansys Software suite. This data includes the can material, which is non-linear strain hardening aluminium allowing for yielding at high strain, can wall variable thickness and loading characteristics. The methodology is then applied to reduce the can weight by optimal distribution of the can wall thickness and redesign the base section whilst revealing an innovative design that fulfils the qualification needs, impacting directly on the material cost, in addition to cost of transport and energy. The authors are awaiting IP clearance to disseminate the optimum design. Meanwhile, analysis on the initial design is permitted.
