This paper explores the distribution of roller elasticthe
rolling area during the rolling process, under the assumption
of roller and without the consideration for heat conduction.
The deformation distribution on the strip surface after rolling
was yzed to confirm that a slight protrusion in the surface of
the cross section can effectively improve the smoothness of
strip In terms of strips, the large deformation-large strain
theory, Lagrangian formulation (ULF) and step by step principle
were used three dimensional elasticplastic analytical model for
aluminumThe flow stress was considered as the function of the
strain anded to deduce the government equation containing
strain rate effects. In the theoretical model and computer
programs of the finite element applied as the basis to
determine whether the simulation results. As for the processing
of contact problems, the roller wasigid body at the beginning
of each step. The increment displace andf strip nodes were
calculated first, and then entered into the first iter The
contact force of strip nodes were distributed to thecause the
roller's elastic deformation. The amount of elasticroller nodes
then compensated for the increment displacement of strip
nodesunt of roller deformation on the increment displacement of
striphe new contact nodal force was derived from the governing
equation ofallowance was also designated to compare the
standards of stripfore and after the iteration, and to
determine whether the iteration was completed.
