The purpose of this investigation is to make the deformation features of the clad sheet metals basically clear from a view point of its press formability. In the present paper, it is shown as an experimental fact that the limiting drawing ratio of the single-clad sheet of commercially pure hard aluminium and soft one changes from better value to worse one than that of each composing sheet, depending on the punch profile radius, the upper and lower side positions of a clad sheet and the ratio of the thickness of each composing sheet. The reasons for these changes are examined by considering the effect of bending conditions on the external surface strain, and the effects of the frictional force at punch profile surface and the traction force at the interface of each composing sheet on the stretching and necking deformation. General explanations for the experimental results are made by summarizing the change of these effects depending on the working conditions and the composing conditions.
