TI  - Shoe-Floor Interactions in Human Walking With Slips: Modeling and Experiments.
LID - 10.1115/1.4038251 [doi]
AB  - Shoe-floor interactions play a crucial role in determining the possibility of 
      potential slip and fall during human walking. Biomechanical and tribological 
      parameters influence the friction characteristics between the shoe sole and the 
      floor and the existing work mainly focus on experimental studies. In this paper, 
      we present modeling, analysis, and experiments to understand slip and force 
      distributions between the shoe sole and floor surface during human walking. We 
      present results for both soft and hard sole material. The computational 
      approaches for slip and friction force distributions are presented using a 
      spring-beam networks model. The model predictions match the experimentally 
      observed sole deformations with large soft sole deformation at the beginning and 
      the end stages of the stance, which indicates the increased risk for slip. The 
      experiments confirm that both the previously reported required coefficient of 
      friction (RCOF) and the deformation measurements in this study can be used to 
      predict slip occurrence. Moreover, the deformation and force distribution results 
      reported in this study provide further understanding and knowledge of slip 
      initiation and termination under various biomechanical conditions.
