Rubber Division ACS Endurica Workshop: Viscoelastic Effects in Elastomers and Impact on Durability

March 23, 2021 @ 9:00 am - March 24, 2021 @ 12:00 pm

Do you want to better understand the dynamic mechanical data generated by your rubber lab? This course will clarify the reasons for the various temperature, frequency and strain sweeps that are used in dynamic testing of elastomers (especially filled rubber) and discuss the impact of the viscoelastic behavior on heat build-up and durability of rubber products. This specialized training will benefit materials engineers, compounders, rubber chemists, product development engineers, R&D scientists and rubber lab managers at manufacturers of tires and rubber parts and companies that supply raw materials.

– Know the key viscoelastic signatures of rubber and how to characterize with testing
– Learn about self-heating (heat build-up) in elastomers
– Understand how strength and fatigue lifetime are affected by viscoelastic dissipation (hysteresis) and temperature

– Overview of viscoelasticity and dynamic mechanical analysis (DMA)
– Key viscoelastic signatures of elastomers and how to effectively characterize with dynamic testing
Glass-to-rubber softening transition
Time(frequency)-temperature superposition
Payne effect
Mullins effect
– Viscoelastic self-heating (heat build-up) and blow-out
– Predicting temperature rises in rubber applications from energy dissipation/hysteresis
– Effects of hysteresis and temperature on elastomer durability
