Concept of critical stiffness. Schematic diagram showing a velocity step at low effective normal stress. A Determination of the critical stiffness for slip instability based friction slip dependence (Ikari et al. 2013). B Determination of the critical stiffness criterion based on RSF parameters derived from inverse modeling, including a linear detrending algorithm (Blanpied et al. 1998; Ruina 1983)
