HSCM.•The proposed model has good potential to accurately model tillage forces.•Different …

Considering the problems of high tillage resistance, high energy consumption, and failure to
break the plow pan in subsoiling caused by the high viscosity of tea garden soil, a new …

The discrete element method (DEM) can accurately predict and describe the motion
behavior of granular materials; it has been widely used in related research in all walks of life …

Highlights•DEM has the potential to predict top soil burial of inversion tillage tools.•Soil bin
tested and DEM predicted forward soil movement show a consistent trend.•DEM simulated …

Historically, most mouldboard plough research has been focused on improving the
performance of the mouldboard itself, with very little focus on other plough components such …

The soil-tool interaction can effectively be modeled with discrete element method (DEM)
when a proper contact model and DEM parameters are applied. The interaction of a single …
