Hyperelastic Material definition
I'm using Creo Simulate, version 4.0
I'm trying to run a structural simulation on a model that has rubber isolation mounts in it. Normally, I would represent the rubber components with linear springs but I don't have any information on the mounts in this case. I know these are non-linear but there is usually a region of the load deflection curve that is nearly linear so approximating with springs has worked okay for me
.
Without a load/deflection curve I'm considering modeling the rubber part and defining a Hyperelastic material. However, I have no idea what to use for the constants. Neo-Hookean needs C10 and D1 and Mooney-Rivlin needs C10, C01 and D1. These parts are made fo 45 durometer natural or Butyl rubber. Does anyone know a source for this kind of information?
