Abstract:The formability of tailor welded blanks is significantly reduced compared with the homogeneous blanks. This phenomenon is caused by the fact that there is a severe change in the material property sideways the welding line. Within 2-3 mm, in case of laser welding maybe less, there is a gradient of mechanical characteristics of materials. The research work presented in this paper deals with numerical simulation regarding forming of a cylindrical shaped part made from tailored blanks (TWBs), having the welding li… Show more
