Hi everyone,

I have a question regarding PRF input file definition. From Abaqus documentation I find out two possibility to define stress ratios. If I understand it right, following definitions should return same results. But the results are totally different. What's error here? Have anyone an idea?

*Material, name=Material-1
*Hyperelastic, Neohookean, Moduli=Long term
0.121199
*Viscoelastic, Nonlinear, SR=0.153206, NetworkId=1, Law=strain
1.692751e-01, 1, 0

*Material, name=Material-1
*Hyperelastic, Neohookean, Moduli=Long term
0.121199
*Viscoelastic, Nonlinear, NetworkId=1, Law=strain
1.692751e-01, 1, 0
*Network Stiffness Ratio, N=1
0.153206

Thank you in advance
