ABSTRACT
This study focuses on the adaptability of discrete element method (DEM) in agricultural machine design. Laboratorial three point bending, compression and dynamic cutting tests were conducted to define the main mechanical parameters and behaviour of corn stalks. For the DEM simulations of the laboratorial tests Timoshenkobeam bonded model was selected. With modifications of thegeometry structure and the input parameters of the contact model, during an iteration process, the right assembly was found. The findings of the study clearly demonstrate that DEM capable of simulating the interactions, among the plants, the parts of the machine, and the appeared loads during agricultural processes.
