Hello there,
I am trying to model a slope. I have some initial von misses stress in ABAQUS. We know that the that Von misses yield strength is two times(2*Su) of undrained shear strength. So in my drained analysis, I need to fix the soil properties before failure so that the slope is stable in existing condition. I am using Mohr Coulomb Failure Criteria. Then I will initiate failure. So, How can I select the parameters (Cohesion and Angle of internal friction) based on my von misses stress? Like,.. I have high von misses stress at the toe like 250 kPa and in others part it varies between 150 kPa to 200 kPa. So, how can I select the parameters?
Thank you for reading this one. Please help me.
