Tillage tool design by the finite element method: Part 1. Finite element modelling of soil plastic behaviour



Tillage tool design by the finite element method: Part 1. Finite element modelling of soil plastic behaviour



Journal of Agricultural Engineering Research 72(1): 37-51



Finite element calculations of draught and vertical forces, soil deformation and normal pressure distribution on the subsoiler face are reported for 4 types of subsoiler. A non-linear, 3D, finite element analysis of the soil cutting process for a standard medium-deep subsoiler, based upon the Drucker-Prager elastic-perfectly plastic material model was used. A mathematical construction of the Drucker-Prager model is presented.
