Item Description: Hardy, S J and Abdusslam, R M, ‘Upper and lower bound limit loads for thin-walled pressure vessels used for aerosol cans’, Advances in Mechanical Engineering, 2009, ID 218536, 1-8, (2009).doi:10.1155/2009/218536This paper is one of a series investigating the optimum shape design and manufacture of aluminium aerosol cans, as a result of a collaborative project with a local can manufacturer. ~96% pure aluminium slugs are used in a back-extrusion process. Since can production rates are very high and material costs are dominant, material saving has a very significant impact on profitability. This research has lead to a three-year contract with Unilever, value £200,000. So far, on the basis of savings identified, it is estimated that material costs can be reduced by ~£1.5m per annum.
