Abstract:

The report deals with one small phase of the problem of mobility for cross-country vehicles, namely a wheel being towed through soft soil. A new concept in soil mechanics is sought which will cope with the problem of the behavior of soil when massive displacements are involved, as occurs when a wheel cuts a deep rut in soft material. It is suggested that such movement of a soil is more in the nature of a flow phenomenon, and an energy-per-unit-volume concept is hypothesized in which the total energy spent area under the load-sinkage curve is divided by the net volume of soil displaced by a penetrating element.
