i did the automatic calibration for the Dobrany and Motol sand and tried to model the soil tests also in Plaxis and then to compare both. For the triaxial test the ExCalibre curve and PLaxis curve are narly the same but for the Oedometer curve there are always big differences.
So my first question is, if anyone of you knows, why there is that difference between ExCalibre and Plaxis for the Oedometer curve?
And the second question is, if anyone knows, if the results (strains) of the Plaxis soil test tool are engineering or true strains?
Attached you can find two figures (two materials), where the difference can be seen very well.
Thanks in advance and kind regards
