An experimental apparatus and a numerical simulation model were built for investigating the dent resistance of lightweight three-piece cans.The dent resistance of raw materials 0.19 mm T4 and 0.17 mm DR7M was compared.It was found that when the thickness reduced from0.19 to 0.17 mm,the dent resistance became about 80%of that before thinning.This provides a guidance for the continuous thinning of three-piece cans.
