    • A new crystal plasticity constitutive equation based on crystallographic misorientation theory 

      Kuramae, Hiroyuki; Nakamura, Yasunori; Sakamoto, Hidetoshi; Morimoto, Hideo; Nakamachi, Eiji (CIMNE, 2011)
      Conference report
      Open Access
      Since plastic deformation of polycrystal sheet metal is greatly affected by its initial and plastic deformed textures, multi-scale finite element (FE) analysis based on homogenization with considering micro-polycrystal ...
    • Microscale electrical contact resistance analysis for resistance spot welding 

      Niho, Tomoya; Kubota, Kenji; Aramaki, Hirochika; Kuramae, Hiroyuki; Ishihara, Daisuke; Horie, Tomoyoshi (CIMNE, 2017)
      Conference report
      Open Access
      Electrical contact resistance is an important parameter for resistance spot welding. In this study, a microscale electrical contact resistance analysis method is pro- posed for resistance spot welding. The microscale ...
    • Multiscale analysis of piezoelectric material by using EBSD-measured realistic model 

      Kuramae, Hiroyuki; Sakamoto, Hidetoshi; Uetsuji, Yasumoto (CIMNE, 2013)
      Conference report
      Open Access
      Material properties of a polycrystal piezoelectric ceramic, a barium titanate BaTiO3, were analyzed by the two-scale crystallographic homogenization method. Threedimensional (3-D) micro-finite element (FE) model was ...
