Finite Element Analysis of Ground Deformations Beneath Moving Track Loads

Changes in soil structure following passage of a tracked heavy machine

“…Gassman et al, 1989;Karafiath, 1984) and for agricultural (e.g., Blunden et al, 1994;Keller et al, 2002;Kirby et al, 1997;Marsili and Servadio, 1996;Rusanov, 1991) and construction applications in particular (e.g. Berli et al, 2003;Berli et al, 2004).…”

Evaluation of link-track performances using DEM

“…Some models are based on constitutive relations; the FEM approach developed by Karafiath [4] is an example of such a model. In practice, because of the difficulty of obtaining the proper parameters for the soil and its behavior as a granular material, the FEM model is unable to provide better accuracy compared with the semi-empirical models [3].…”
