Dynamic Mechanical Analysis and Fatigue Testing Webinar
Friday, November 13, 2020
11:00 am
Sponsored by ARDL
This webinar will be an overview of dynamic mechanical analysis (DMA) and fatigue testing methods and will give examples of non-tire applications (including silicone applications) where these test methods are relevant. The DMA overview will discuss strain, temperature, and frequency sweeps performed in tension, compression, or shear. It will also review the data generated by those sweeps including storage modulus, loss modulus, tan delta, Payne effect and Mullins effect. Fatigue testing methods that will be discussed will include Demattia crack growth, Monsanto fatigue-to-failure, Ross flex crack growth and Goodrich flexometer (heat buildup and blow out).
