Abstract
A procedure for calculating residual stresses is developed. It is based on the energy approach and the Tresca criteria of strength and plasticity and includes the main technological parameters of tube making. Relationships are derived to estimate the ultimate strain during the production of axisymmetric hollow metal billets.
