Webinar: The Fatigue Limit of Rubber

This two-hour webinar will introduce industry professionals to the concept of fatigue threshold in elastomers and how to use this material parameter to develop highly durable rubber products. A technical background is recommended. This webinar will cover:

General fatigue crack growth behavior of elastomers
– Power law response
– Tear strength
– Fatigue threshold (limit) / intrinsic strength

How to measure fatigue limit
– Lengthy fatigue crack growth measurements
– Tear strength of swollen samples or at high temperature
– Cutting method

Insights into developing a product to operate below the fatigue limit
– Interplay of part geometry, loading conditions, and material properties
– Importance of crack precursor size, as influenced by raw materials selection and mixing quality
