Dear all,
After carefully reading the matlab drivers of hypoplastic models, I was wondering whether the driver can simulate triaxial extension tests. As I change the constraints to reflect triaxial extension, the result is clearly not correct. My aim is to simulate different intermediate principal stress tests. Any suggestions or comments will be appreciated. Thank you!
