Dear all,
When I check the umat file of sand hypoplastic modeling, I find there are two parametesr(p_t(2), bulk_w(15)) without any definitions. Could someone kindly explain the exact meaning for these two parameters?
Thanks a lot
Joe

Dear Joe,
P_t is kind of cohesion that shifts the mean stress. This cohesion is often quite helpful to achieve convergence.
Bulk_w is the bulk modulus of water. You can find some more information about the parameters at the following webpage https://web.natur.cuni.cz/uhigug/masin/plaxumat/node5.html
