Determining Components of Soil-Metal Sliding Resistance

ABSTRACT An experimental technique and method of analysis for determining the adhesive and frictional components of the sliding resistance between soil and another material were developed and tested. By controlling the loading history of the sliding interface, the effects of nor-mal stress and initial sliding-path length on the adhesive component were determined. Normal stress and sliding-path length affected the adhesive component greatly but had very little effect on the frictional component.
