Viscoelastic Effects in Elastomers and Impact on Durability - LIVE ONLINE March 23-24, 2021 

9:00 a.m. - 12:00 p.m. (EST) each day

Do you want to better understand the dynamic mechanical data generated by your rubber lab? This live, online workshop 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 deep-dive, hands-on workshop 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.

 Workshop Objectives

  • 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

Workshop Details

Presented LIVE online over two sessions from 9:00 a.m. - noon EDT. As a special service to attendees, Dr. Robertson will be available for individual questions during office hours from 1:00 - 3:00 p.m. daily during the course.


You will learn Endurica's insights on 

  • 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


The workshop features live lectures and live exercises focused on specifying, executing and interpreting numerical simulations of fatigue behavior. This course is a LIVE training event and link to the presentation of each class will be made available to registrants for their reference/review. These links will be active for seven days after the class date so attendees will have time to make up classes they may not be able to attend live. This course will NOT be distributed or broadcast beyond this time period.  


Dr. Chris Robertson is an international authority on polymer science, viscoelasticity / rheology, and rubber compounding for performance. He brings over 15 years of materials research and product development experience at tire and rubber companies and raw materials suppliers.  Chris is co-inventor of 32 patents, co-author of 62 publications in peer-reviewed journals, and serves as Editor-in-Chief of Rubber Chemistry & Technology.


Endurica LLC reserves the right to cancel a scheduled training course if the minimum class size is not met. In the event of a cancellation, Endurica LLC will make every attempt to notify registered participants within five working days. Payment made for a canceled course will be refunded in full or applied to another scheduled training course.

Participant cancellations must be received at least 10 working days in advance. Registrations canceled by participants less than 10 working days before the training course begins are subject to a 50% cancellation charge. For cancellations occurring on the first day of a scheduled training course, and for "no shows," the full tuition fee is non-refundable.
