    Delamination behaviour of high strength vibration damping sheet in V-bending test (2018)
    Institute of Physics (IOP)

    Publication Date: 2018-09-22
    Description: High strength vibration damping sheet (VDS) consists of two high strength steel sheets and a viscoelastic polymer core with high vibrational damping characteristics. In this study, high strength VDSs with were fabricated with dual phase (DP) 590 steel sheets with 0.7mm of thickness as outer skins and polymer core with very thin thickness. To investigate the effect of different characteristics of the polymer core on delamination behaviour during press bending operation, three types of polymer cores were considered, which are polyethylene, epoxy and acrylic based adhesives and the V-bending tests were performed using the manufactured VDS. In addition, finite element analysis (FEA) was carried out to analyze the influence of the normal/shear directional characteristics of the polymer core on delamination behaviour in the V-bending test. As a result, it could be shown that different delamination behaviours were caused by the three types of the polymer core having different normal/sh...

    Form-fit joining behaviour between an aluminium tube and sheet using electromagnetic forming (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-09-22
    Description: The electromagnetic forming (EMF) process is a typical high speed forming technique using Lorentz forces generated by interaction between the magnetic field and induced electric current. Recently, researchers have discussed form-fit joining using tube compression by EMF without additional connection elements for application in the industry. This paper provides analysis into the form-fit joining behaviour achieved by tube expansion using EMF. The aluminum 6063 tube was inserted into an aluminum 7075 sheet with hole of the same size as the diameter of the tube, and they were fixed on the coil. The flanging and bulging of the tube were simultaneously conducted by the magnetic force with given charging voltage, and then the form-fit joining was achieved between the tube and sheet. To investigate the effect of the input voltages, the experiments were performed with various charging voltages from 5.7 kV up to 11.1 kV. In addition, the connection strength of the joined specimen was mea...
