Webinar: The Fatigue Limit of Rubber
February 28, 2024 @ 10:00 am - 12:00 pm
Webinar Description: 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
Price: Free for Members / $99 Non-member
