SPECIAL SESSION 7:
EXPERIMENTAL INVESTIGATIONS AND MODELLING IN POLYMER MECHANICS: STATE OF THE ART AND FUTURE TRENDS (SS7)
Polymers and polymer components are highly important in a wide range of industrial applications, from such as, bearings and seals to bonds and coatings or pressure vessels and piping. Since these components are used in various areas of engineering, they are naturally exposed to very different processing or service conditions, mixing both environmental influences of chemical or biological substances and complex mechanical or thermal solicitation profiles. Furthermore, polymers’ response and failure show strong time and temperature dependencies. Representative examples could be the high-cycle fatigue of polymer components combining long term mechanical load accumulation to environmental influence, the physical ageing of lacquer coatings, the thermo-oxidative ageing of elastomeric bearings and bonds or the dynamic-thermo-mechanical behaviour of vibration isolators and tires.
This session will focus amongst other topics on different ageing effects as well as on new challenges in polymer modelling and components design. Experimental and theoretical researchers are welcome to present their meaningful results and methods.
