Nonlinear modelling of a special forming process

In modern metal–working industry, according to the optimal design procedure as well as optimal manufacturing, the computer simulation of the both processes is required. The presented paper deals with numerical modelling of cold flattening–rolling problem. On the basis of finite element algorithm the computer program is made and tested on an example. Large elastoplastic updated Lagrangian Hencky formulation is used, while roll–workpiece friction problem using friction layer technique is solved.
