ABSTRACT:
A tubular metal member undergoes expansion transverse to the longitudinal axis of the member. An axial compressive load is applied to the member parallel to the member's longitudinal axis, and the member is allowed to deform transversely to said axis. Procedures are employed to control the deformation of the member, to prevent the member from buckling, and to ensure that the ends of the member will be expanded uniformly with the remainder of the member.
