Hi all! I was looking around for theoretical background in depth related to Hyperelastic material model (Especially Ogden, Mooney-Rivlin). Any suggestion and references on the related topic (deduction of material constants) would be very appreciated. I have checked out with some documentations of FE software which didn’t help me that much.
Thank you very much!
Normally it is quite hard to get the hyperelastic parameters. For general info. about them, please see our documentation here: Hyperelastic materials. For detailed study, please see: ABAQUS theory documentation (Please see section 4.6).
If you want to have the constants for specific model, you can pass over the stress and strain data of your material and I can compute it for you.
Hi @ahmedhussain18! Thank you so much for your prompt reply!
I was looking for more in-depth theoretical background for the said material model. I will look into the documentations and take this opportunity to seek your valuable help on this topic. I will revert you back soon for your help if you don’t mind.
You could also look at the SimScale blog article on the determination of material parameters: How to Choose a Hyperelastic Material Model for your Finite Element Analysis?.
You could also check out the blog in the upcoming days, as there are some articles scheduled regarding elastomers.
