INFLUENCE OF THE FEED ANGLES ON THE STRESS-STRAIN STATE OF AN INGOT IN SCREW ROLLING

The orientation of the stress components in the metal under a roller i s established on the basis of the known macroshear trajectories. Relat ions for the stress-strain state of the ingot in screw rolling are der ived by an existing analytical method; these relations allow the chang e in the stress field to be determined as a function of the strain con ditions. The stress-strain state of the ingot is analyzed for various rolling conditions.
