VISCOELASTIC EFFECTS IN ELASTOMERS AND IMPACT ON DURABILITY

Introducing our Newest Class:

 

Do you want to better understand the dynamic mechanical data generated by your rubber lab? This one-day 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. 

New for 2020: Now Available Live Online!
Our live, online version of Viscoelastic Effects in Elastomers and Impact on Durability features the live lectures and insights of Dr. Christopher Robertson. This course is a LIVE training event and a 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.  

August 4-5, 2020: Lectures 9:00 a.m. – Noon EST with additional time available for questions during Office Hours 1:00 – 3:00 daily during the course duration. Register Online

Course 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

Format

This one-day course includes lectures and classroom exercises focused on understanding viscoelasticity and its impact on strength and fatigue of rubber materials. Lunch and snacks are included. 

Agenda

Day 1: 8:30 am – 3:30 pm

  • 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

Due to COVID19, no live, in-person version of this course is currently scheduled.

Instructor

Dr. Chris Robertson is an international authority on polymer science 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 55 publications in peer-reviewed journals, and serves as Associate Editor of Rubber Chemistry & Technology.
