摘要：
This paper presents a model for prediction the stress state in agricultural soil below agricultural tyres in the driving direction and perpendicular to the driving direction which are different from one another, using the finite element method. In present, one of the most advanced methodologies for modelling the phenomenon of stresses propagation in agricultural soil is the finite element method, which is a numerical method for obtaining approximate solutions of ordinary and partial differential equations of this distribution. In this paper, the soil has been idealised as an elastoplastic material by Drucker-Prager yield criterion.
