- Annotation: To substantiate target ranges of static and dynamic coefficients of friction in the system “ footwear inner surface – hosiery – foot” ensuring functional efficiency of the foot during walking and preservation of plantar aponeurosis performance. Static and dynamic coefficients of friction were determined experimentally under conditions of natural skin moisture using a universal tribological tester. The computational substantiation was performed based on Amontons-Coulomb model with physical interpretation of friction as a combination of adhesive and deformation components. It was established that the coefficient of friction strongly depends on the fibre composition of hosiery and on the type of material used for footwear inner surface. The introduction of an intermediate textile layer fundamentally alters the tribological contact regime and the distribution of tangential stresses. Based on the computational analysis, minimum admissible and functionally reasonable values of the coefficient of friction were determined for the heel and forefoot regions of the said organ.
