Abstract: A general finite strip analysis method is presented for the
forming process analysis of channel steel. For the first time, a
theoretical model of elastic-plastic large deformation spline
finite strip method based on the updated-Lagrange method is
introduced to metal forming field. The method is employed to
analyze the displacement field, the stress field and the strain
field between two stands during channel steel forming process.
The information is valuable to the production. It is proved that
the method is available for the analysis of the complicated
channel steel forming.
Key words: Roll
