EXPERIMENTAL STUDY OF ADHESION APPEARING BETWEEN PLATE AND CLAY

The present research aims at obtaining fundamental knowledge of adhesion appearing between steel disk plate and clay by experimental means. Bentonite, Japanese acid clay and deepsea sediments were used as testing materials. Two different kins of adhesion could be measured: one is the separating force when a plate is pulled up from the clay surface vertically, and the other the lateral plate drag on clay surface. Adhesion data were measured for the variation of several parameters such as the contact pressure of plate, the cohesion of clay itself, the area of plate, and the surface roughness of plate. The data analysis showed that the contact pressure and the cohesion of clay had significant roles for the appearance of adhesion and the drag. These results would provide useful technical information for the design of civil engineering machinery, sea bottom cable ploughs and deep ocean manganese nodule collectors.
