Hi everyone,
I am currently working on creating a triaxial compression test simulation in EDEM, since I want to use this model into the calibration toolkit and compare my results with some experimental data I have. I know triaxial test is not directly available in the calibration kit options, but I have been doing this by modifying the uniaxial compression model. I just need to applied a radially constant confining pressure (or at least that's my thoughts). What I have done is started with the uniaxial compression test template, use the sleeve geometry but disable the sleeve motion, so it remains in place during the test and add a force controller applying a force that represents he 30 kPa in X and Y directions and left z=0, and I also include a damping coefficient of 15 hz.
However, when I do that the sleeve kind of disappear in the middle of the simulation, and I don't honestly see the particles have a confinement effect. have anyone done this before?
is this the right approach to do it? or is there a better method to apply the constant radial confining pressure?
I appreciate any advice, suggestion or shared experiences. Thank you
Isabel
