Study on asymmetrical sheet rolling by the finite element method

Adopting the DEFORM software for the finite element analysis, this study si mulated steady-state plastic deformation of the sheet at the roll-gap durin g asymmetrical sheet rolling. Using FEM code DEFORM, the effects of roll sp eed ratio, roll radius ratio, friction factor ratio upon the curvature of t he rolled product and rolling force were systematically discussed. With a v iew to verifying the validity of the study simulated, a series of experimen ts on asymmetrical cold sheet rolling using Aluminum sheet as specimen are carried out. The comparisons between numerical and experimental results sho w good agreement. Therefore, this numerical model using DEFORM software can offer useful knowledge for designing the pass-schedule of asymmetrical she et rolling.
