Status of research on the plastomechanical fundamentals of rolling and drawing processes

Among the processes for plastic deformation of steel, rolling of strip, plate, and sections, and drawing of wire, bars, and tubes are of great importance. A survey is given showing to what extent the plastomechanical fundamentals of these forming methods have been developed. Theory is mainly directed towards the calculation of the deformation force and the flow of material. The governing influences are of geometrical, kinematical, thermal, tribological, and material-scientific kind. Starting from the basic equations of continuum mechanics, the mathematical methods of similitude, visioplasticity, energy bounds, elementary plasticity, slip line fields, and finite elements are briefly characterized.
