Dear Mina,

You can always define your own User Defined Soil Models. Here's an article with more information about it (also found in our manuals): communities.bentley.com/.../plaxis-user-defined-soil-models

Dear Stefanos,

Thank you for your reply,

The GSK model is similar to the Hoek-Brown model in that a curved yield surface is used in place of
the Mohr-Coulomb yield surface. It is shown in the below paper,, section 4 and figures 3 and 4.

If there is no shortcut, i was wondering if it is possible to define new material laws into plaxis...

Thank you,

Mina

Dear Mina,

Apologies, can you please explain what the GSK material is? Reading the abbreviation, it does not ring a bell.
