  • Refill Friction Stir Spot Joining for aerospace aluminum alloys 

    Boldsaikhan, Enkhsaikhan; Fukada, Shintaro; Fujimoto, Mitsuo; Kamimuki, Kenichi; Okada, Hideki; Duncan, Brent; Bui, Phuonghanh; Yeshiambel, Michael; Brown, Brian M.; Handyside, Alan Bruce (Springer, 2017)
    Refill Friction Stir Spot Joining (RFSJ) developed by Kawasaki Heavy Industries (KHI) is a derivative technology of friction stir spot welding for joining aerospace aluminum alloys. The aerospace aluminum alloys were ...

  • Multi-scale characterization of an adhesive bondline with fabrication induced defects 

    Fang, Eugene; Lua, Jim; Zhang, Yongjie Jessica; Lai, Yicong; Seneviratne, Waruna P. (DEStech Publications, Inc., 2015)
    A multiscale characterization of an adhesive bondline is performed to investigate the fabrication defects dependent failure mechanisms of an I-beam under four point bending. To obtain a realistic representative volume of ...

  • The use of neural network and discrete Fourier transform for real-time evaluation of friction stir welding 

    Boldsaikhan, Enkhsaikhan; Corwin, Edward M.; Logar, Antonette M.; Arbegast, William J. (Elsevier, 2011-12)
    This paper introduces a novel real-time approach to detecting wormhole defects in friction stir welding in a nondestructive manner. The approach is to evaluate feedback forces provided by the welding process using the ...

  • Performance evaluation of child safety seats in far-side lateral sled tests at varying speeds 

    Ghati, Yoganand; Menon, Rajiv A.; Milone, Mary; Lankarani, Hamid M.; Olivares, Gerardo (Association for the Advancement of Automotive Medicine, 2009-10-05)
    Protection of children in Child Safety Seats (CSS) in side impact crashes has been a topic of recent studies. The objective of this study was to evaluate the performance of CSS in far-side impacts through a series of sled ...

  • SPH -- Lagrangian study of bird impact on leading edge wing 

    Guida, M.; Marulo, F.; Meo, M.; Grimaldi, A.; Olivares, Gerardo (Elsevier, 2011-02)
    Results from the experimental tests are given so that they can be used to validate numerical models and promote the use of the numerical tools in aircraft design and certification process. The explicit finite element ...
