Hello All,

I have a question regarding how to find material model coeffiecients.I dont have any experimental data with me to find coeffiecients of mooney -rivlin and ogden material models by fitting the curves.Is der any way to find coefficients of these materials with out experimental data.

I want to find these coefficients for muscle tissue .

thanking you ,

with best regards,

Bhargava Palakurthy

What FE software are you using? Most FE software comes with a built-in ability to find the material parameters for both the Mooney-Rivlin and the Odgen models.

For these simple materials, my own [URL= http://polymerfem.com/content.php?9-MCalibration ]MCalibration[/URL] program also works well. The MCalibration application has the additional benefit of being able to calibrate many other and more advanced material models.

Dear Jorgen,

Thanks alot for your reply.Im using FEBIO software for my simulation .I dont have any stress strain data .How can i use MCalibration software to find material coefficients.Can you help me regarding this .

thanking you ,

with best regards,

If you send me a [URL= http://polymerfem.com/sendmessage.php ]private [/URL]message with:
- Your name and company/university affiliation
- The MAC address of your computer

Then I will send you a trial license to the software and instructions how to download it.
