Validation of a Multiscale Hysteresis Mechanics Model in Predicting Oily Shoe-Floor Friction Across Surfaces With Varying Finishes.

ABSTRACT: Shoe-floor friction, quantified by the coefficient of friction (COF), is an important predictor of the risk of slip-and-fall accidents. There is a commonly used model of friction by B. Persson that describes viscoelastic dissipation due to hysteretic properties of rubber. Applied to shoe-floor friction, the model calculates the COF by using two primary inputs: (1) the multiscale surface topography of floor tiles and (2) the time-dependent material properties of the shoe rubber. While this theory is well accepted by many theoreticians and modelers, there is almost no direct experimental validation. Here, the model is tested by comparing against experimental measurements of COF using three different designs of shoes, ten different porcelain-tile floors, and canola oil as a contaminant. The r
