Abstract. The objective of this paper was to study and simulate the switchgrass stems and cutting tool interactions during a particle size reduction process. Finite element analysis method was used to model the structure of a switchgrass stems and cutting tools. An ultrasound-assisted blade was designed and its modal analysis was conducted. Transverse-direction isotropic finite element model simulation was used to analyze the mechanical behavior of a switchgrass plant under shearing forces. The proposed method has a potential to provide an accurate method of improving the performance of cutting/grinding tools in biomass processing. The finite element model developed in this study can be extended for the simulation of other biomass materials and plants.
