Les pneus sont soumis \u00e0 de fortes d\u00e9formations cycliques lorsque les v\u00e9hicules roulent sur la route. Lorsqu'ils sont expos\u00e9s \u00e0 des conditions routi\u00e8res difficiles, la dur\u00e9e de vie des pneus est compromise par de nombreux facteurs, tels que l'usure du fil, la chaleur g\u00e9n\u00e9r\u00e9e par la friction, le vieillissement du caoutchouc, etc.<\/p>

En cons\u00e9quence, les pneus ont g\u00e9n\u00e9ralement des structures de couches composites faites de caoutchouc charg\u00e9 de carbone, de cordes de nylon et de fils d'acier, etc. En particulier, la composition du caoutchouc \u00e0 diff\u00e9rents endroits des syst\u00e8mes de pneus est optimis\u00e9e pour fournir diff\u00e9rentes propri\u00e9t\u00e9s fonctionnelles, y compris, mais sans s'y limiter, un fil r\u00e9sistant \u00e0 l'usure, une couche de caoutchouc amortissant et une couche de base en caoutchouc dur.<\/p>

Un test fiable et reproductible du comportement visco\u00e9lastique du caoutchouc est essentiel pour le contr\u00f4le qualit\u00e9 et la R&D des pneus neufs, ainsi que pour l'\u00e9valuation de la dur\u00e9e de vie des pneus usag\u00e9s. Analyse m\u00e9canique dynamique (DMA) pendant Nanoindentation <\/a>est une technique de caract\u00e9risation de la visco\u00e9lasticit\u00e9. Lorsqu'une contrainte oscillatoire contr\u00f4l\u00e9e est appliqu\u00e9e, la d\u00e9formation r\u00e9sultante est mesur\u00e9e, permettant aux utilisateurs de d\u00e9terminer le module complexe des mat\u00e9riaux test\u00e9s.<\/p>
