Artificial compaction is one of the most dangerous forms of degradation of\nagricultural soil. Recognized as a phenomenon with multiple negative effects in terms of\nenvironment and agricultural production, soil compaction is strongly influenced by the size of\nexternal load, soil moisture, size and shape of footprint area, soil type and number of passes.\nKnowledge of soil behavior under compressive loads is important in order to prevent or\nminimize soil compaction. In this paper were developed, by means of the Finite Element\nMethod, various models of soil behavior during the artificial compaction produced by the\nwheel of an agricultural trailer. Simulations were performed on two types of soil (cohesive and\nnon-cohesive) with known characteristics. By applying two loads (4.5 kN and 21 kN) in\nfootprints of different sizes, were obtained the models of the distributions of stresses occuring\nin the two types of soil. Simulation results showed that soil stresses increase with increasing\nwheel load and vary with soil type.
