STRAIN ANALYSIS OF LATERAL EXTRUSION PROCESS①
Liu Zuyan and Wang Erde

School of Materials Science and Engineering,Harbin Institute of Technology, Harbin 150001, P. R. China

Abstract:The strain distribution of equal-cross section lateral extrusion(ECSLE) has been simulated by finite element method. Considering the effect of friction and the width of sample, the simulation results are very close to the reality. The simulated results showed that, around the corner of die, the strain is distributed by sharp layers, and the gradient of the layers is very large, which means that the deformation is just plane shear deformation; the larger the width of sample or the smaller the friction, the more uniform the strain distribution is.

 

Key words: equal-cross section lateral extrusion finite element simulation strain equivalent true strain
