Abstract:
In some flat rolling procedure, the normal pressure in the contact zone
shows double peaks. According to the rolling conditions in the reference
paper, the flat rolling procedure is simulated by dynamic explicit
elasto-plastic finite element method. The results from the simulations
are good agreement with those from the experiments. The normal pressure
obtained from simulation shows double peaks. Through the analysis of the
bite stage and the whipping stage in the rolling procedure, the factor
of the double normal pressure peaks is obtained. The elastic zone after
contact zone of the strip is the main factor and it will bring the
double normal pressure peaks together with contact friction.
