摘要：

In the present work, the material parameters for power law and the coefficient of friction are obtained using inverse analysis by measuring exit strip temperature and slip. The procedure makes use of a finite element model for deformation and an analytical method for the estimation of temperature. A heuristic optimization algorithm is used for this purpose that minimizes the error between the measured and estimated flow stresses. The method is verified by conducting some numerical experiments.
