Uni-axial tension test

[vahed]

hi,
I used ASTM D412 for uniaxial tension test (die c).after that I interred the obtained data to ABAQUS and evaluated the material. My problem is that "constants that I received for Mooney-Rivlin model are C01= -25.2763478 and C10=15.9242173" and I think that this constants are wrong! where is the problem?

I agree, those parameters sounds quite strange!

My guess is that your experimental data is incorrect or that the data is noisy. Can you check the data again?

thank you for your reply,
I checked my experimental data again and I found that I used wrong data for extracting C01 and C10, after I corrected the errors I received:
C01=0.71 and C10=0.77 , do you have any opinion about this results?
sincerely

That sounds pretty good to me.
