Study was conducted in a laboratory glass-sided soil bin with dry compact loam soil with 5.2% (d.b.) moisture content. The specific objective of this study was to determine the effects of flat rigid tine rake angle (forward angle between tine face an

Studies were conducted in a laboratory glass-sided soil bin with dry compact loam soil (c = 0.02 kPa, Φ = 20° and cone index 210 kPa) with the specific objective of observing the effect of flat tine rake angle and aspect ratio on soil failure patte

The effects of low-to-medium slip, lug spacing and moisture content on lug forces in clay soil were investigated in a laboratory soil bin with the help of two model lugs. Perpendicular and radial soil reactions on the lug were measured and they were

The finite element method (FEM) was used to model cutting of wet clay by a wide tine using measured soil stress-strain characteristics as input data. The incremental method was used to deal with this geometrically nonlinear problem and correspondingl

Studies conducted in a laboratory soil bin filled with dry sand indicated that the nature of soil reactions on tines of 90° rake angle were cyclic for tine aspect ratios (width/depth) of 0·6 and greater. For tine aspect ratio of four, soil reaction

Tests of soil cutting by wide tines were conducted in wet clay soil. Force-displacement curves were obtained and the soil deformation patterns were observed and analysed with the help of a painted grid. The tine experiment showed that the soil deform
