Hello I encountered some result issues while using SPH and SCM tire longitudinal test benches. When the tire is in the high slip zone (slip ratio>0.8), the calculated results of the two seem to be inconsistent. The SCM results indicate that the longitudinal force of the tire is saturated, but the SPH calculation results show that the longitudinal force increases when the slip ratio is greater than 0.8. After studying the literature, I found that both of these situations have occurred. Which simulation result should I trust? Is the reason for this phenomenon that SCM cannot simulate soil deformation under high slip conditions during the calculation process using empirical models? If possible, I would greatly appreciate it if you could provide relevant suggestions. The attachment is a comparison of the simulation results of SPH and SCM in the literature "An Overview of Tire Ground Contact Modeling Approaches for Surface Mobility Applications", which is consistent with my experimental results. Thanks. Chen
