Hello Friends,
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?
For example,
Ogden 3 coefficients
M1= 0,000031095
exp1=1,0632600
M2=0,658686
exp2=2,6659000000
M3=0,0038656200
exp3=3,0326200000
thank you in advance
best regards

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