Investigation of an Alternative Finite Element Procedure: A One-Step, Steady-State Analysis.

Abstract

A one-step, steady-state 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 multi-step analysis using a commercial finite element code if it becomes computationally expensive. A steady-state 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 three-dimensional one-step code or to do a multi-step transient analysis using existing code.
