STRESS CALCULATION APPLIED TO A COIL AND OPTIMIZATION OF COILING TENSION

The coiling stage is important in terms of quality of cold rolled stri ps, as it occurs several times during the production process. It is th erefore to control it in order to avoid coiling defects such as heart shape and loosing. Thus, we are taking interest in the mechanical mode lling of coiling, so as to study the occurence of some defects and to optimize the coiling tension.
