THE DEVELOPMENT OF LAND LOCOMOTION MECHANICS REQUIRES A DEPARTURE FROM SOIL MECHANICS AS APPLIED TO HIGHWAY DESIGN. EXTREMELY LARGE SHEAR AND SINKAGE DEFORMATIONS THAT EXTEND WELL BEYOND THE ELASTIC OR LINEAR STRESS-STRAIN RANGE OF SOIL ARE FACED WHEN DEALING WITH OFF-ROAD VEHICLE DESIGN. EQUATIONS DESCRIBING SOIL PRESSURE SINKAGE RELATIONSHIPS AND SHEAR STRENGTH DEFORMATION ARE PRESENTED. THE MOTION RESISTANCE OF A VEHICLE IS PROPORTIONAL TO THE SINKAGE AND THE TRACTIVE EFFORT IS PROPORTIONAL TO THE SHEAR STRENGTH. THE DEVELOPMENT OF EQUATIONS DESCRIBING THESE PROPORTIONS PERMITS THE PREDICTION OF VEHICLE PERFORMANCE.
