Analytical methods for Crack propogation/fatigue life in elastomers
Analytical methods for Crack propogation/fatigue life in elastomers
(OP)
I am searching for a numerical method that allows me to determine the fatigue life of a rubber roller due to cyclic loading on the outside diameter that is compressive only. All I can find to date are industry-specific test methods per ASTM or ANSI for example. Thanks for any leads or ideas you may have.

N=(k/g)^5
N=number of cycles
g=alternating shear strain
k=a material constant. This varies with each elastomer compound, but the paper used a value of 11 for isoprene.

Can you provide a more specific reference to the paper you are talking about? I performed a Google.com search with the key words: Vertica, Lord, Corporation. Here is the link:
http://www.google.com/search?sourceid=navclient&q=Vertica+Lord+Corporation
The first result from this search references the following:
I. Chopra, Perspectives in aeromechanical stability of helicopter rotors, Vertica, 14, 4 (1990), pp. 457-508.
Do you know how one can access this particular journal?
Thanks!
