Abstract: With an accurate parametric equation of the contact arc,the kinematically admissible velocity and strain rate fields are established in this paper.A precise formula to calculate the average strain rate in rolling is dedued by the parametric integral and the integral mean value theorem.It is compared with the traditional formulas through an actual measured example.

Key words: rolling equation of the contact arc, parametric integral, mean strain rate
