Characterizing Elastomer Fatigue Behavior for Analysis and Engineering - NOVEMBER 9 - 11, 2020

Elastomers are outstanding in their ability to repeatedly endure large deformations, and they are often applied where fatigue performance is critical. Their macromolecular structure gives rise to unique behaviors, and so appropriately specialized experimental methods are needed to characterize, analyze, and design for durability. This 3-day course will give you powerful approaches to anticipate, diagnose and solve fatigue-related issues.
