Abaqus nonlinear Strain-Stress Curve
Feb 15, 2016 6:34 am
I am using ogden material model and ı, have my coefficients. I am running analysis with abaqus. In Result of uniaxial tension analysis, strain stress curve is linear. But it must be nonlinear.
How can I solve this problem? Could you please help me?
Ogden 3 coefficients
thank you in advance

Not sure why. It looks like you are using a non-linear elastic model.
Are the strains large enough?
