Interest in the analysis of behaviour and stress distributed over the blade has increased in recent years. An investigation into a 2-dimensional model to compute the effect of different shapes of agricultural plough blades (C-blade, L-blade and I-blade) on nodal displacements and stress distributions was carried out using MicroField finite element software. To simulate the boundary conditions to which the blades were subjected, the blades were assumed as moving at a certain depth in the soil and the blades were clamped along the root of the blade. The distributed pressure created in a steady motion condition was analysed as normal and tangential pressure that acted upon the blade. The same distributed soil pressure was assumed to be subjected uponthe blades from zero depth of soil to the lower part of the blade. The L-blade created the highest displacements and stresses over the blade.
