Elastic tool behaviour in cold rolling

by

Elastic tool behaviour in cold rolling Reiner Kopp, Martin Franzke Institute of Metal Forming, RWTH Aachen University, Germany. DOI: https://doi.org/10.7494/cmms.2008.1.0185 Abstract: An important issue for realistic simulation of the cold rolling process is the consideration of the tools as elastic structures. The material flow is strongly influenced by the elastic deformation of the tools. Due … Read more
