The mechanical impedance of soil is well known to influence the shape formation of storage roots of root vegetables strongly. Contact interaction between the root and soil become important in the growth and shape formation of the storage root. Thi...

The objective of this study was to develop a mechanical model for cohesive, plastic behavior of soil by the Distinct Element Method (DEM). The DEM has been applied to solve problems of soil-tool interaction. There is still a need for improving the...

In this paper, numerical simulation of soil loosening by a vibrating type subsoiler is carried out by means of the Distinct Element Method (DEM). As the DEM model used in this study considers the continuity of compacted soil layer, cracking and fr...

A mechanical model of soil is constructed using the Distinct Element Method (DEM) which makes it possible to analyze the discontinuous property of soil. To discuss the applicability of the soil model by the DEM, a bar penetration test was conducte...
