Abstract
The objective of the present work is to study materials properties and performance of the footwear thread to develop and implement an analytical-numerical model capable of simulating their performance. The numerical results simulation was carried out, analyzing the sliding mechanisms of shoe-floor and evaluating the contact pressure and vertical stress. An experimental procedure, supported by a numerical model, was implemented for computing the evolution of the tangential force over several load increments.
Highlights
Efficient shoes should provide adequate foot protection, safety, and comfort during operative tasks
The coefficient of friction (COF) is affected by several factors related to the shoe design, the flooring design, and the liquid contaminant between the surfaces in contact [2]
Some in-depth analyses were performed to acquire a better knowledge of material characteristics, using Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Analysis (DMA)
Summary
Efficient shoes should provide adequate foot protection, safety, and comfort during operative tasks. The coefficient of friction (COF) is affected by several factors related to the shoe design, the flooring design, and the liquid contaminant between the surfaces in contact [2]. For this reason, the interface conditions between the shoe and ground surface need to be accurately investigated during kinematic and kinetic studies. The force platforms are the preferred measurement devices to evaluate the effects of the combined GRF components These platforms are mechanical friction-testing devices generally belonging to two groups: portable devices applying low normal forces proportional to human body mass using a simple specimen, and whole shoe testers using a normal specimen and applying conditions very close to real ones [4]
