Hi I am trying to view the mean effective pressure in the soil and the onset of plasticity at different parts in the soil but I am not too sure how to do it, would you be able to help. The soil is modelled with SSP brick elements.

The model in question is attached.

Are you referring to the mean pressure of the stress tensor? If not, could you provide the equation you need?
