o-ring fatigue

[relengr]

I have a situation in which an o-ring is subjected to pressure variations. In time, the o-ring can fail which results in a leak. A previous thread on this website discussed some of the problems with applying S/N techniques to rubber. My question is are there some references available that explain how to characterize elastomer type components under cyclic loading?

Any help is appreciated.

. . . a good reference may be the book:

How to design with rubber, Carl Hanser publisher

edited by A.Gent
This book gives an excellent overview on fatigue of rubber components etc.
