Elastomer Mechanical Properties

[Andronicus1717]

Specifically I'm looking for a resource that can provide me with basic material property information for common elastomers such as Neoprene(R) for the purposes of flat gasket joint analysis. Stress/strain curves and other such data would be very helpful.

I understand that elastomers material properties can vary greatly based on a great many things however common practice is to specify a basic material and a durometer i.e. Neoprene 50-60 durometer Shore A. Is such information enough to get meaningful material property data?

Have you tried www.matweb.com ?

I checked the ANSYS materials which has NEOPRENE listed for explicit analysis. The data is more for shock analysis than what I think you need, but just in case.

Density: 1.439 g cm^-3
Shock Equation of State Linear
Gruneisen Coefficient - 1.39
Parameter C1 - 2785 m s^-1
Parameter S1 - 1.419
Parameter Quadratic S2 - 0 s m^-1

I have never used this stuff, but here is a reference
http://en.wikipedia.org/wiki/Mie-Gruneisen_equation_of_state

just in case it's helpful.
