Numerical analysis of soil ploughing using the particle finite element method

Abstract

This contribution illustrates some results from a parametric analysis of the factors affecting soil ploughing. The numerical simulations rely on the Particle Finite Element method, a method known for its capabilities to tackle large deformations and rapid changing boundaries at large strains. A total stress analysis – assuming a quasi-incompressible elastic model along with a Tresca plastic model - is used to simulate a clayey soil behavior. As a first step, a two-dimensional geometry is used and the effect of contact roughness in the horizontal force along the chip formation is assessed.
