Prédiction de la performance d’adhérence de caoutchoucs pour semelles : Analyses tribologique, mécanique et numérique

Abstract : This thesis addresses the grip of hiking and trail-running shoes. We focus on cross-linked, silica-filled, outsoles rubbers. Our aim is to predict grip quality perceived by users. To do so, we explore multidisciplinary techniques. We consider three methodologies: tribological and mechanical characterizations and modelling.-Tribological study is based on footwear standard (personal protective equipment). We discuss an adaptation for outdoor outsoles. We set test conditions and surface preparations required for a pertinent and reproducible characterization.-Mechanical study deals with hysteresis phenomena as a major contributor to rubber friction on wet surfaces. We try to set a predictive characterization based on dynamic mechanical analysis (DMA) by estimation of hysteresis loss in mechanical conditions representative of friction solicitations.-Tribological (static-dynamic transition) and mechanical (hyperelasticity or viscohyperelasticity obtained from tension: large cyclic loading-unloading) phenomena are implemented with finite element modelling. 2D and 3D modelling would support future lugs development.Each methodology is independent considering identical physical mechanisms. Based on mechanics, tribology and surface science or modelling we study the relationship between rubber deformation and friction.
