Hallo,
I have a 3D and a 2D model. I use Mohr Coulomb parameters for my material. I tried to convert them into Drucker Prager parameters.
For my 3D model I used the equations from the triaxial test:
Mohr Coulomb: ?=35° , ? = 11 => Drucker Prager: ?= 54.81°, ? = 22, K= 0.778
For my 2D model I used the equations from plaine strain response:
Mohr Coulomb: ?=35° , ? = 11 => Drucker Prager: ?= 43.81°, ? = 22, K= 1
My results do not correspond to each other.
Please Help me. I do not know what I am doing wrong.
