Dear all,
I’m facing trouble in calculating NO. 16 parameter in the UMAT for sand hypoplasticity by Dr. Masin, any help will be really appreciated especially with an example.
Best Regards,
Aysar

Hi, this is not a parameter, but state variable, which is measured and not calibrated (volume of voids over volume of solid).
Hi,
Thanks for your reply, this void ratio is at the initial state?
Yes please
