Shoe –Floor Interactions in Human Walking With Slips: Modeling and Experiments

We present results for both soft and hard sole material. The computational approaches for slip and friction force distributions are pr esented 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 repo rted 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 var ious biomechanical conditions.
