Abstract：
|
|
Finite element simulation of the extrusion forming of self-piercing semi-tubular rivet was carried out by DEFORM-2D software.Extrusion process of the rivet,distribution of stress and strain,and load-stroke behavior were analyzed.Many simulations were carried out under different extrusion speeds,temperatures and rivet materials.Load-speed curve,load-temperature curve and load-materials column were used to analyze the extrusion dies load under different speeds,temperatures and rivet materials.The results offer the principle for the experiments.
