WebNov 17, 2008 · In the presliding regime the adhesive forces owing to asperity contacts are dominant, and thus the friction force is primarily a function of displacement rather than velocity. The reason for this behavior is that the asperity junctions deform elastoplastically, thus behaving as nonlinear hysteretic springs. WebAug 2, 2024 · As such, if the tip is located inside the red area (Fig. 14), then the elastoplastically deformed zone is still constrained inside the individual particle and hence only involves a monolithic zone, and the corresponding measurement just probes the mechanical properties of the individual phase. However, if an indent is located within the …
