Abstract : A onestep, steadystate finite element analysis procedure that is applicable to the problem of determining stresses and the driving force to pass a plane through soil at constant velocity is developed. This type of analysis is shown to be an alternative to doing a multistep analysis using a commercial finite element code if it becomes computationally expensive. A steadystate problem allows the time dependence to be expressed as a space dependence and thus solved in one step. The feasibility of this type of analysis is demonstrated but more investigation is needed in soil failure at the plow tip and an associated soil plasticity model before any attempt is made to produce a production threedimensional onestep code or to do a multistep transient analysis using existing code.
