Hi,
I am wondering how it would be possible to analyse stress/strain relaxation in the CRS soil-test-facility in PLAXIS 3D?
I am currently using the Soft soil creep model and used the optimise parameter function to match with the lab data. However, when running the test, the strain increment value is "0" at start of relaxation but the output just shows a plateau. Whereas, the lab data shows a small decrease before plateau. How would is be possible to model this?
Also, how would I be able to analysis the pore pressure/suction of this while doing so?
Any suggestions??
