Abstract: The mechanical properties and cylindrical deep drawability experiments for an aluminium/steel sheet metal laminate are conducted. The effects of the annealing temperature on the mechanical properties and the anisotropy of the laminate are investigated. The influence of punch profile radius on the limiting drawing ratio is examined. It is found that the limiting drawing ratio of an aluminium/steel laminate depends on the blank-set condition of whether a punch-contact metal (inter-laminate) is aluminium or steel. The reasons for this phenomenon are especially discussed.
