Data Set for Validation of a multiscale, hysteresis mechanics model in predicting oily shoe-floor friction across surfaces with varying finishes

This data set is described within the manuscript, “Validation of a multiscale, hysteresis mechanics model in predicting oily shoe-floor friction across surfaces with varying finishes” [1].

Shoe-floor friction is an important contributing factor to the risk of experiencing a slip and fall event. A theoretical model by B. Persson has been developed to describe viscoelastic energy dissipation caused by multiscale surface topography of a hard material as it slides against an elastomer with time-dependent material properties. Yet, this model has not been extensively validated for shoe-floor friction. In this data set, we report the time-dependent material properties for the three shoes described in [1], the model predictions for coefficient of friction based on the model when considering all length scales (“full-length-scale”) and when excluding small scale features (“limited-length-scale), and experimentally measured coefficient of friction values. The coefficient of friction values are reported for the three shoe materials and 10 floor surfaces.
