Influence of the Strengthening Curve on the Axial Stress in Round Rod on Drawing

Influence of Strain Hardening on the Force in Cold Strip Rolling

“…(2) by the approximations in Eqs. ( 6), (9), and (12) when n < 1 decreases the mean equivalent yield point (over the deformation region) and hence decreases the calculated technological load [8].…”

“…Replacing σ s by σ s0 in Eq. ( 5), Tselikov derived the following equations for the axial and normal contact stresses (7) (8) where K = βσ se ; q 0 = σ 0 /K; q 1 = σ 1 /K; σ 0 and σ 1 are the tensile stresses at the input and output of the deformation region; λ 1 = h x /h 1 .…”
