Finite Element Analysis during Shape Rolling Processes
ABSTRACT
This paper used three-dimensional finite element code-deform to analyze the deformation behavior of material at the rolling-gap during shape rolling of T-profiled and H-profiled sheet. The rigid-plastic model was used. The rolls are assumed to be rigid body and the change of temperate during rolling is ignored.
In T-profiled sheet rolling, 1-pass and 2-pass rolling were included. There-dimensional deformation of the sheet was analyzed and the filling ratio at the roll gap, the spread of the sheet, rolling force, the curvature of products were predicted etc. Comparison between analytical and experimental results was made to verify the suitability of the DEFORM software.
In H-profiled sheet rolling , the stress, strain, velocity distribution of material was investigated and the filling ratio was analyzed at the H shape flange during the different reductions. These results can offer knowledge for the design of actual H-profiled sheet rolling.
