| Abstract: | The finite element method is used to investigate soil cutting process. It is of help to researchers to thoroughly understand the reality of this phenomenon.By means of this method the soil stress distribution,soil deformation,position of soil failure,normal and tangential pressure distribution on tillage tool face can be predicted.The up-to-date research progress of the finite element analysis of soil cutting is reviewed.Some problems existing in current research work is pointed out and future research by using finite element method is also given. |
