Two-dimensional Thermo-mechanical Analysis of Flat Rolling Using Rigid-plastic Finite Element Method

Abstract

A finite element code for two dimensional steady-state thermal analysis has been developed, and combining it with a rigid-plastic finite element code for steady-state deformation analysis, the thermo-mechanical analysis of hot rolling of flat products was conducted for plate rolling and hot strip rolling conditions. The importance of the thermo-mechanical analysis was discussed based on the results of the computation. Through the present work it was concluded that thermo-mechanical analysis is indispensable for the precise estimation of stress and strain distributions in the roll-bite.
