• Description:
  Slip and fall accidents cause frequent occupational injuries. Despite recent evidence that boundary lubrication is relevant to slipping, few studies have examined the mechanisms that contribute to shoe-floor friction in this lubrication regime. This study aims to identify the contributions of adhesion and hysteresis to friction in boundary lubrication. Three shoe materials (40 Shore A hardness polyurethane, 60 Shore A hardness rubber, and 70 Shore A hardness rubber), two floor materials (vinyl and marble), and six lubricants (water, 1.5 % detergent, 25 % glycerol-75 % water, 50 % glycerol-50 % water, 75 % glycerol-25 % water, and canola oil) were tested at a single sliding speed (0.01 m s-1). Dry adhesion and hysteresis were quantified for each of the shoe-floor combinations and lubricated adhesion was quantified for all shoe-floor-fluid combinations. The contribution of adhesion and hysteresis to shoe-floor-lubricant friction was affected by both the shoe and floor material due to differences in hardness and roughness. Lubricated adhesion was complex and multifactorial with contributions from the shoe, fluid, shoe-floor interaction, floor-lubricant interaction, and shoe-lubricant interactions. A simple regression model including two fluid coefficients and the dry adhesion friction force was able to predict 49 % of the lubricated adhesion friction variability.
