Hello all,
I am using the clay hypoplsticity model in Abaqus. As shown in the picture, I have to construct the stiffness desegregation curve to calibrate the R value. Can I directly extract the shear stiffness (G) value in Abaqus software or I have to calculate it from the stress-strain curves? or any recommendation please!
