Effect of rate on soil shear strength and soil-metal friction I. Shear strength

The effect of deformation rate on the shear strength of a sandy and a clay soil has been examined in a new laboratory rig designed to shear soil in the range equivalent to 0.0015-5 m/s sliding speed. Soil cohesion was found to vary logarithmically with deformation rate over a wide range of moisture...

Summary:The effect of deformation rate on the shear strength of a sandy and a clay soil has been examined in a new laboratory rig designed to shear soil in the range equivalent to 0.0015-5 m/s sliding speed. Soil cohesion was found to vary logarithmically with deformation rate over a wide range of moisture contents. The soil internal friction angle was independent of deformation rate and the residual shear strength did not vary in a consistent manner with deformation rate. The results have important bearing on the efficiency of soil working operations such as cultivation, earth moving and traction.
