The study of the phenomena that occur during the compression of oilseed grains is important to increase the oil extraction performance. The Finite Element Method (FEM) is an advanced engineering tool for modeling complex systems, assisted by CAD (Computer-Aided Design), predicting behaviors, avoiding destructive tests and reducing costs and operating time.The aim of this work was to model the mechanical behavior of canola grains subjected to compression.A FEM model was used under a linear compression load, using Ansys® software. A homogeneous 3D solid model of the grain was generated, with relevant physical properties such as shape, size, density, Poisson´s ratio and modulus of elasticity. The interaction (points and type of contact) between the grain and the upper and lower compression plates were evaluated. No horizontal movement of the bodies was assumed, avoiding the translation of the seed under the applied load.The validation of the FEM was carried out by comparing the results obtained by the model with those obtained experimentally in the compression tests under the same conditions. The model adequately represented the Force-Deformation curves obtained experimentally, indicating that the FEM is a valid tool for the study of the mechanical behavior of canola grains, providing valuable information to optimize and design the processing of this oilseed.
