Analytical and Numerical Evaluation of Wire Flat Rolling Process Based on the Slab Method and DEFORM-۳D

Considering slab method, a three-dimensional analytical model was adopted to evaluate the rolling pressure, force and torque in symmetrical wire flat rolling. Due to the effectiveness of the shear friction model to express the frictional state in the bulk metal forming, thus, it was used to define in slab formulation. In this paper, the plains strain condition no longer is valid and, the strain on z direction must also be taken into account in calculations. The resultant differential equations were solved numerically by Rung Kutta method and MATLAB software. It was concluded that as shear factor rises in the range of o.۴
