Abstract:

The report deals with the off-road vehicle problem generally identified as slip-sinkage which involves the identification of the sinkage required to provide flotation of a vehicle and that induced by the shearing of soil in order to develop traction. Sinkage is defined as consisting of three components static sinkage to provide flotation in the absence of shear deformation equilibrium sinkage to allow the invoking of maximum soil shear strength and slip sinkage which occurs, within limits, so long as the shear deformation rate is non-zero. The study involved both a theoretical analysis and an experimental program. The theoretical analysis relied heavily on existing analyses of strip loads found in co-called classical soil mechanics.
