Abstract The warm stretching process of U-sharped AZ31 magnesium profile with thin wall was simulated by 3D thermo-mechanically coupled finite element model. Variation of temperature filed and stress filed were simulated in four different temperature model. The mould preheating, temperature filed homogenization and the follow-up heating improved efficiency of bending were simulated. Results showed that ten seconds preheating time was significant, heat exchange could be decreased by follow-up heating and temperature field homogenization. Stable temperature field is investigated to apply in warm tension rotation bending of AZ31 magnesium alloy profile in this paper.

Key words： magnesium alloy profile warming bending numerical simulation heating model
