Hi,
I know that I can extract the BB model constants from two cmpression test with different strain rate, though I have a couple of questions:
- what would be the strain rate for the unloading part of the compression tests?
- Is there any way to get the constants wih tensile tests? I have all standard hyperelastic test data, stress relaxation test data and uniaxial test data with different strain rates. The strain limit for all mentioned tests are limited to our application strain (30%)
Thank you,
