- •
Different types of simple shear apparatus including stacked-ring, NGI and Cambridge types are modeled using DEM.
- •
The stress state, principal stress/strain rotation and normal force distribution are investigated.
- •
Non-coaxiality was observed before the critical state.
- •
A good insight into test results interpretation procedure is provided.
