Summary

A theory for axisymmetric drawing of tube and rod is presented and compared with experimental results. The equations derived enable drawing force, die pressure and interlayer shear stress between the different material combinations to be determined. It was found that the magnitude and direction of the shear stress at the bi-metal interface and the bi-metal thickness ratio had a marked effect on draw load.
