摘要: Abstract A finite element model based on solid mechanics was developed with ABAQUS to study the material flow in whole process of friction stir welding (FSW), technique tracer particles. Simulation results indicate that pattern particles around pin is spiral movement. There are very different patterns at upper and lower parts weld. The surface has downward movement affected by shoulder upward pin. velocity periphery stirring higher than bottom can be rotated a few times, agreeing well previous experimental observation tungsten
