, Zhenjiang 212003, China) Abstract: A finite element model of self-piercing riveting (SPR) of glass fiber reinforced thermoplastic (GFRTP) was developed based on LS-DYNA software. The SPR process..., increasing the pip angle of die is useful for improving the self-locking performance of SPR joint, while increasing the strength of rivet can effectively improve the strength of SPR joint. Key words: self......

. The cohesion of CTB rises as the curing age and cement content increase. However, the enhancement in internal friction angle is trivial and negligible. It should be noted that the failure pattern of CTB... strength; volumetric strain; elastic modulus; cohesion; friction angle Cite this article as: XU Wen-bin, LIU Bin, WU Wei-lü.

Simulation of Fiber Pushing-out Test张亚芳Faculty of Civil Engineering,Guangzhou University摘 要:The stress distribution on the failure progress of fiber pushed-out test was studied. A numerical program, developed by meso-damage mechanics, was adopted to simulate the whole failure process of interface debonding and fiber pushing out. From the simulation......
