In the course of this research, a so-called mass-spring method was implemented in an in-house developed two-dimensional discrete element software, which enables the simulation of deformable, tear-able bodies, such as plant residues (stems or roots), or other agricultural fibrous materials. The operation of the numerical methods was illustrated with simulations where a rigid plate was moved horizontally against a plant residue modeled by the mass-spring method, pulled in an assembly of particles modeled by the discrete element method, and pulled in a combination of these. When evaluating the results, it was found that the improved numerical methods are able to work stable both separately and in interaction with each other, thus in the future it is possible to take plant residues as stems and roots into account during the simulations of the tillage process with their coupled application.
