A modified model to predict soil cutting resistance
Abstract A modified three-dimensional model to determine soil resistance has been established from the McKyes-Ali model. The model is based upon minimizing the total soil resistance to determine theExpand

A non-linear 3-D finite element analysis of soil failure with tillage tools
Abstract A non-linear 3-D finite element model was developed to study the soil failure under a narrow tillage blade. The weighted residual method was applied to formulate the finite element model.Expand

Numerical modelling of soil stress and pressure distribution on a flat tillage tool using computational fluid dynamics
Soil pressure on tillage tools and its distribution over the tool surface are important factors for tool design with respect to tool wear. Soil stresses due to the tool motion are also very importantExpand

Quick finite element analysis of soil tool interactions
Abstract The calculating speed of a finite element analysis of soil tool interactions is an important key factor to determine whether the method will be accepted by the designers or not. SeveralExpand

Effect of tillage speed and straw length on soil and straw movement by a sweep
Abstract Crop residue cover protects soil from erosion caused by water and wind. High amounts of residue are not needed and part of crop residue needs to be removed by bailing and part of the cropExpand

Draft-speed relationship of simple tillage tools at high operating speeds
Abstract Field experiments were conducted with five different blades operated vertically in sandy loam and clay soil types up to a speed of 18 m s −1 to determine the draft-speed relationships atExpand
