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?
