    • New ductile fracture criterion for prediction of internal fracture in skew rolling 

      Yamane, Koji; Shimoda, Kazuhiro; Kuroda, Koichi (CIMNE, 2019)
      Conference report
      Open Access
      Skew rolling is the process of reducing the diameter of a round billet. In this process, internal fracture may occur in the rolled material. This phenomenon is known as the Mannesmann effect. While there has been great ...
    • Three-dimensional numerical analysis of rotary piercing process 

      Yamane, Koji; Shimoda, Kazuhiro; Yamane, Akihito (CIMNE, 2017)
      Conference report
      Open Access
      Three-dimensional numerical analysis of the rotary piercing process was performed by the rig d plastic finite element method. Rotary piercing, also known as the Mannesmann piercing process, is a hot rolling process that ...
