Dear all,

Here are two numerical results of UCS modeling. For the SPH model, contact force in the interface between the plate and sample increases nonlinearly when compared with FEM results (*MAT_PLASTIC_KINEMATIC). Could you tell me what cause could lead to this? I have tried to refine the particles spacing ,but it doesn't work.
