Methods of determination of normal and tangential contact stresses with allowance for deformation development against time at forge-rolling

Abstract

The methods of determination of normal and tangential stresses at forge rolling with allowance for deformation development against time is described in the paper. The obtained formulae are presented, they characterize the dynamics of deformation center change, and they are used for determination of contact normal and tangential stresses. The results of the performed tests are described. The discrepancy between the theoretic design results and the experimental data at test of the proposed methodology is 1.7-4 % that confirms the possibility of its use for determination of contact normal and tangential stresses.
