Effect of tube size on electromagnetic tube bulging LI Zhong(李 忠), LI Chun-feng(李春峰), YU Hai-ping(于海平), ZHAO Zhi-heng(赵志衡) School of Materials Science and Engineering, Harbin Institute...; Abstract: The commercial finite code ANSYS was employed for the simulation of the electromagnetic tube bulging process. The finite element model......
micro groove copper(MGC) tube. Then the bonding of MGC tube was reached because of intensively plastic deformation of MGC tube under pressure. It is found that the plastic deformation area of the cold welding of MGC tube can be divided into three sections. The deformation of micro grooves in each section was investigated; the influence of the dimensions of cylindrical heads on the weld joint shape......

Received 21 April 2010; accepted 10 September 2010 Abstract: The friction coefficient between tube and die in guide zone of tube hydroforming was obtained. In hydroforming, the tube is expanded......
J. Cent. South Univ. (2016) 23: 869-879 DOI: 10.1007/s11771-016-3134-9 Dynamic rupture and crushing of an extruded tube using artificial neural network (ANN) approximation method Javad Marzbanrad1... are usually used in automobile and train structures to absorb the impact energy. Previous researches show that thin-walled circular tube has the highest energy absorption under axial impact amongst......
