Outline of Final Research Achievements

In this study, we conducted two different types of friction and wear experiments using two different materials; acrylic resin and compliant polymer gels. In the latter case, we applied large sliding velocities comparable to the sound velocity of a material. As a result, we succeeded in discovering unconventional frictional behaviors; in the first series of experiments, we observed transient frictional response even under constant experimental conditions. In the second series of experiments, friction coefficient exhibits an abrupt increase and deformation of gels becomes abnormal when the sliding velocity exceeds S wave velocity.
Through these studies, we were able to demonstrate giant responses in frictional behavior.

Academic Significance and Societal Importance of the Research Achievements

まず,できる限り単純な実験系を構築することで,通常の実験で見られる複雑な挙動をシンプルに理解することが可能であることを示すことができた.また,摩擦挙動のその場観察によって,摩擦状態の適切な把握ができることを示すことができた.さらに,実験と理論を併用した研究アプローチにより,現象の詳細な理解が可能であることを確認できた.これらの成果は,今回取り組んだ摩擦・摩耗現象に限らず,さまざまな系に対しても適用可能であると考えられ,広範な現象,分野への波及効果が期待される.
