STRESS FIELD UNDER SLIPPING RIGID WHEEL

THE WHEEL-SOIL INTERACTION PROBLEM (WHEN THE SOIL REACHES THE FAILURE STATE) IS ANALYSED. THE STUDY REPRESENTS A SOIL MECHANICS APPROACH TO EXPLAINING THE FAILURE CONDITIONS AND THE STATE OF STRESS UNDER A WHEEL ON THE VERGE OF SPINNING. THIS IS EXPERIMENTALLY MODELED BY A WHEEL RESTING ON SOIL WHOSE TRAVEL IS RESTRICTED. AS THE DRIVING TORQUE ON THE WHEEL'S AXLE IS INCREASED, FAILURE STATE IS REACHED WHEN SMALL SLIPPING OF THE WHEEL STARTS. THE WHEEL IS THEN ON THE VERGE OF SPINNING. VALUES FOR SLIPPING AND THE ANGULAR VELOCITY ARE DEFINED, AND THE CASE OF STEADY STATE SOIL FLOW UNDER A SPINNING WHEEL IS DISCUSSED. THE CALCULATION OF THE RADIAL AND TANGENTIAL STRESS DISTRIBUTIONS, BASED ON THE ASSUMPTION THAT THE WHEEL-TO-SOIL COHESION AND FRICTION VALUES ARE LONGER THAN THE COHESION AND ANGLE OF INTERNAL FRICTION OF THE SOIL MASS IS DESCRIBED. THE AUTHORS COMMENT ON EARLIER DISCUSSIONS ON THE PAPER AND AGREE THAT IN VIEW OF THE OUTLINED MISCONCEPTIONS OF THE DEFINITION OF THE PROBLEM, INTENT OF ANALYSIS, AND METHOD OF APPROACH, UNDERSTANDING OF THE RESULTS OBTAINED AND APPRECIATION OF THE PAPER WOULD BE DIFFICULT.
