    • Contact area measurement of micron-sized metal-coated polymer particles under compression 

      Bazilchuk, Molly Strimbeck; Sumigawa, Takashi; Kitamura, Takayuki; Zhang, Zhiliang; Kristiansen, Helge; He, Jianying (Journal article; Peer reviewed, 2019)
      The contact problem of a sphere under compression by a rigid plate is pertinent to understanding electrical contact formation in anisotropic conductive adhesive (ACA) applications. However, no work has experimentally ...

    • Deformation and fracture of micron-sized metal-coated polymer spheres: an in situ study 

      Bazilchuk, Molly Strimbeck; Sumigawa, Takashi; Kitamura, Takayuki; Zhang, Zhiliang; Kristiansen, Helge; He, Jianying (Journal article; Peer reviewed, 2018)
      In situ imaging and analysis of the mechanical behavior of micron‐sized metal‐coated polymer particles under compression is reported. A nanoindentation set‐up mounted in a scanning electron microscope is used to observe ...

    • Simultaneously toughening and stiffening elastomers with octuple hydrogen bonding 

      Zhuo, Yizhi; Xia, Zhijie; Qi, Yuan; Sumigawa, Takashi; Wu, Jianyang; Sestak, Petr; Lu, Yinan; Håkonsen, Verner; Li, Tong; Wang, Feng; Chen, Wei; Xiao, Senbo; Long, Rong; Kitamura, Takayuki; Li, Liangbin; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2021)
      Current synthetic elastomers suffer from the well-known trade-off between toughness and stiffness. By a combination of multi-scale experiments and atomistic simulations, we demonstrate a transparent unfilled elastomer with ...

    • Static assessment of nanoscale notched silicon beams using the averaged strain energy density method 

      Gallo, P; Sumigawa, Takashi; Kitamura, T; Berto, Filippo (Journal article, 2018)
      This paper extends the averaged Strain Energy Density (SED) method to the static assessment of notched components at the nanoscale. First, in situ micromechanical testing of notched nano-cantilever beams made of single-crystal ...
