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.
