I need to perform an analysis to estimate the compression force of an O-ring. I know that a non-linear analysis is better but I think 20% compression of an o-ring is not too bad and I just need an approximation of the compression force.

My question is can I use the Flexural Modulus of EPDM as the Young's Modulus? Also, is there a Flexural Modulus for EPDM? What is the coefficient of friction for EPDM on steel?

Thanks,
