Need help to solve Hyper-Elastic model (Yeoh Mat type)

sandeepballiwar

Hello Everyone,

I’m trying to solve one Hyper-elastic model with Yeoh Material type.

Sample model is in attachments, Can you please check it once and let me know if I’m missing anything.

 

Elem Type: 8 Node CHEXA

Prop: PLSOLID

Material: MATHE and mat model is YEOH model. (coeff of C1, C2 and C3). I have taken the coefficients from journal

 

Note: I’m able to solve the same model with Mooney-Rivlin material type (C1, C3 and C4 as material coefficients)

 

 

Any kind of help is highly appreciated.

 

Thank you so much in advance.!

In Yeoh model, we need to provide the values of C10, C20 and C30.

 

In the fem file, the values are filled in the slots for C01, C02 and C03.
