THEORY FOR A TOWED WHEEL IN SOIL

THE REPORT DEALS WITH ON 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. /AUTHOR/
