Chapter 2

Modelling of Terrain Behaviour

An understanding of terrain behaviour under vehicular load is of importance to the study of vehicle–terrain interaction. In this chapter, various approaches to modelling terrain behaviour are reviewed.

In the past, modelling the terrain as an elastic medium or as a rigid, perfectly plastic material has been widely adopted. Modelling the terrain as an elastic medium, together with the theory of elasticity, has found applications in the study of soil compaction and terrain damage due to vehicular traffic. Modelling the terrain as a rigid, perfectly plastic material, together with the theory of plastic equilibrium, has found applications in the prediction of the maximum traction developed by off-road vehicles ...
