Optimal Upsetting of Composite Cylinders

  • A. M. LokoshchenkoEmail author


The upsetting of a composite cylinder in frictionless creep is analyzed in energy terms. Three loading programs that lead to upsetting of the cylinder by the same amount in the same time are compared. Variational analysis indicates that the kinematic loading program is best for industrial use.
