Effect of Speed on Soil Failure Patterns in Front of Model Tillage Tools 650691

Tests of flat model tillage tools in two artificial soils indicate that soil failure breakout patterns could be predicted for slow speeds in loam-like soil but, with increase in speed and change to a clay-like soil, the failure changed from breakout of soil segments to continuous flow. High-speed movies of the failure patterns enabled calculation of acceleration forces, shearing strain, and normal strain and also revealed reasons for increase in force with increase in speed. Variables were type of soil, tool angle of 15–90 deg to the horizontal, and tool speed of 0.5–2.5 mph.
