I am working on the example of “Genesis and Testing of a Soft-Bonded Material”. The goal is to obtain a strength value from the uniaxial test, and a few triaxial tests to calculate cohesion and friction angle to be used in slope stability models.
When I run the simulation with my laboratory-obtained parameters I get strangely high strength value (around 500 MPa), while my triaxial are around 50 to 100 MPa.
These are my input parameters - from the laboratory data and slope simulations:
[igap = 0.0*davg ]
[emod = 42.8e9 ]
[kratio = 2.5 ]
[fric = 2.31 ]
[ten_mean = 19.6e5 ]
[ten_std = 0.0 ]
[coh_mean = 19.6e6 ]
[coh_std = 0.0 ]
[soft = 0.0 ]
[cut = 1.0 ]
Is there a difference between running a UCS with and without using domain distortion?
If I run a simulation for ucs and triaxial shouldn’t I get consecutively increasing data?
Thank you for your input,
Agata
