Geostudio V.S. ABAQUS Results Comparation in CK0DC Condition

Dear all,

I'm using the ABAQUS 6.14-4 and Geostudio 2022.1 to simulate the CK0DC test (Drained triaxial compression test on K0 consolidated clay), the soil material model is MCC (Modified Cam-clay), and the model parameters keep the same in two applications. The main purpose is to see if it's the same as the stress-strain path (i.e. q-εa curve, where εa is the axial strain, q is the deviatoric stress) in different OCR (Over-consolidation ratio) conditions. However, I found that the results given by these two software are very different, I DON'T know where the key point is. Is there anyone who could help me? I'd appreciate it. Warm Regards, Chou.

Attached are the detailed model files of ABAQUS AND Geostudio.

    Hey!

    Thank you so much for getting in contact with us

    Generally speaking, the difference in results is likely due to a wrong boundary condition in either GeoStudio or ABAQUS. Our external examples "Triaxial tests on Modified Cam Clay soil" and "Parameterizing the Modified Cam Clay Model", which simulate a consolidated drained condition, might be helpful as a sample project to verify their model setup.

    We will look up the files in order to get a deeper answer

    We'll get in touch!
