Hi everyone, I am doing a simulation of electromechanical coupling effect of a composite (treated as hyperelastic material)- PDMS included with liquid metal. I want to select Odgen model for PDMS because I see some posters say this model fits well with experimental data. However, I don't have experimental data to fit my curve, but since PDMS is a common material, I wonder if there is some library of the parameter of set-up models of common hyperelastic materials? Thank you so much!

Dear Yongyi,

I don't believe there is an inbuilt PDMS hyperelastic material. You may try to search literautre for stress-strain curves and then perhaps model it using Ogden from previous measured parameters. You said some posters have this data, surely they would have supplied the graph for you to roughly ready of the data you need.

Have you tried this?

Regards, TY
