Physical Properties of Rock, Soil and Water Soil and Rock Mechanics Resistance of soil and rock to 1. tensile, compressive and shear stresses o is the most important type of resistance governing the stability of rock masses o stress: force/unit area (Nm -2 ), same units as pressure o tensile stress: pulling apart causing a change in volume (strain, e.g. angular deformation) o compressive stress: crushing or collapsing causing a change in volume o shear stress: deformation involves sliding within a body causing no change in volume but a change in shape (strain) o tectonic stresses (isostasy, orogenesis) are often tensile and compressive; but exogenic stresses (gravity and fluid stresses) are shear stresses 2. abrasion by solids moving over a rock surface (ice or rock fragments carried in wind, water, snow, ice or under the force of gravity; is controlled by the harness of constituent minerals and cementing agents 3. transport by fluids, i.e. bed shear stress Behavior of rock 1.
