[SSS10-10] Rebuilding normal-stress-modulated rate-and-state friction from adhesion theory and Griffith energetics

*Daisuke Sato¹ (1.Japan Agency for Marine-Earth Science and Technology)

Keywords:Friction law, Normal-stress dependence, Griffith energetics of fracture

Conventional friction laws suffer from their inabilities to describe frictional motions under normal-stress modulations. Thus, we constrain possible functional forms of friction laws under normal-stress modulations, based on adhesion theory and Griffith energetics, very robust bases of frictional failure.
