Numerical Simulation of Spin-Blind-Riveting of Magnesium and Fibre-Reinforced Plastic Composite

Abstract:

Spin-blind-riveting (SBR) is a newly developed joining process, which combines the advantages of conventional blind riveting and flow drilling screws. With this technology, it is possible to join two different materials by one-sided accessibility without the need of pre-drilling holes. This complex process cannot be simulated by 2D finite element method. Therefore, a more realistic 3D finite element model for the SBR process is developed using the commercial software package ABAQUS. The applicability of this work is demonstrated for joining magnesium alloy AZ31B and carbon-fibre reinforced plastics. Dynamic effects, thermomechanical coupling, material damage laws, and contact criterion were taken into account in the model. The Johnson–Cook material constitutive equation was used, considering the effects of strain, strain rate, and temperature on material properties. Finally, through simulation, the joint formation, stress distribution and riveting temperature were obtained. Furthermore, a series of experiments were carried out to validate the simulation results. The numerical results are in a good agreement with the experimental results and confirm the promising properties of SBR joints between metal and fibre-reinforced plastics.
