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 reactions were observed to be cyclic for all the tine rake angles studied (15-140°), These variations were found to be closely related to the observed soil failure patterns. Wave ratio (wave length/tine depth) for tines with a rake angle of 90° increased with increase in tine aspect ratio up to four. The amplitude of cyclic variations in draught increased with tine width for a rake angle of 90°. |
