“…The treatment of localized shear, which is caused by the action of tire lugs, for example, is realized by DEM, but cannot be directly expressed by conventional FEM. An algorithm for the implementation of dynamic FE-DEM for soil-tire system interactions, with examples of the simple vertical sinkage and horizontal travel of a tire was previously proposed by the authors (16), (17) .…”

“…Since there is an inherent problem that large computational time is required for contact check and contact reaction calculation in DEM, it is quite natural to utilize both merits of FEM and DEM to compensate for the demerits of each method (14) - (16) . For soil-tire interaction analysis, a reduction in DEM calculation time can be expected by reducing the total number…”

Soil-tire system interaction is a fundamental and important research topic in terramechanics. We applied a 2D finite element, discrete element method (FE-DEM), using FEM for the tire and the bottom soil layer and DEM for the surface soil layer. Satisfactory performance analysis was achieved. In this study, to clarify the capabilities and limitations of the method for soil-tire interaction analysis, the tractive performance of real automobile tires with two different tread patterns-smooth and grooved-was analyzed by FE-DEM, and the numerical results compared with the experimental results obtained using an indoor traction measurement system. The analysis of tractive performance could be performed with sufficient accuracy by the proposed 2D dynamic FE-DEM. FE-DEM obtained larger drawbar pull for a tire with a grooved tread pattern, which was verified by the experimental results. Moreover, the result for the grooved tire showed almost the same gross tractive effort and similar running resistance as in experiments. However, for a tire with smooth tread pattern, the analyzed gross tractive effort and running resistance behaved differently than the experimental results, largely due to the difference in tire sinkage in FE-DEM.

“…For this reason, modelling began to be applied in terms of the characteristics of the substrate. The bases of this new line of investigation were studies of interactions between soil and an overlying object (Nakashima and Wong 1993;Abo-Elnor et al 2004;Fervers 2004;Nakashima and Oida 2004;Mulungye et al 2007). …”

“…Particle based modeling such as DEM (discrete element modeling) and GD (granular dynamics) [40][41][42][43] is a very powerful technique for granular materials, because it simulates mechanical interactions between granular micro scale particles and their collective interactions with tools and machines in a macro scale. It is challenging to develop a reliable method for determining the mechanical parameters of each particle so that the model can represent macro level behavior such as different soil failure patterns (e.g., share plane failure, brittle failure, flow failure, bending failure, and tensile failure 44 ).…”

Real-world processes are often combinations of deterministic and stochastic processes. Soil failure observed during farm tillage is one example of this phenomenon. In this paper, we investigated the nonlinear features of soil failure patterns in a farm tillage process. We demonstrate emerging determinism in soil failure patterns from stochastic processes under specific soil conditions. We normalized the deterministic nonlinear prediction considering autocorrelation and propose it as a robust way of extracting a nonlinear dynamical system from noise contaminated motion. Soil is a typical granular material. The results obtained here are expected to be applicable to granular materials in general. From a global scale to nano scale, the granular material is featured in seismology, geotechnology, soil mechanics, and particle technology. The results and discussions presented here are applicable in these wide research areas. The proposed method and our findings are useful with respect to the application of nonlinear dynamics to investigate complex motions generated from granular materials.
