摘要：
This paper reports the numerical simulation of the 3D material flow in friction stir welding process by using finite element methods based on solid mechanics.It is found that the material flow behind the pin is much faster than that in front of the pin.The material in front of the pin moves upwards and then rotates with the pin due to the effect of the rotating tool.Behind of the pin,the material moves downwards.This process of material movement is the real cause to make the friction stir welding process continuing successfully.With the increase of the translational velocity or the rotational velocity of the pin,the material flow becomes faster.
