Hi all,
Can anyone give a clarification on the material property (parameter 22) in the hypopplasticity umat for clay on Abaqus.
My understanding is that these parameters are defined as user material constants. So if you defined an initial void ratio for a given stress state for parameter 22 in the list of parameters, would that cause the void ratio to remain constant during the analysis? (which would be wrong)
Cheers,
Hashmi
