Article: normal stress
A Dictionary of Earth Sciences;      42 words ...normal stress (σ) The stress which acts perpendicularly to the plane to which a force has been applied. Normal compressive stresses (with positive values) inhibit sliding along a plane; normal tensile stresses (with negative values) separate rocks along a plane.

Article: stress
A Dictionary of Earth Sciences;      67 words ......Stress can be resolved into two important components. Compressive (tensile) stress (σ) acts normal to the surface (see NORMAL STRESS ) and changes the volume of the body; shear stress (τ) acts parallel to the surface and changes the shape of the body...

Article: compressive stress
A Dictionary of Earth Sciences;      42 words ...compressive stress The stress produced by forces acting on a unit area of rock, which can be resolved into a normal stress and a shear stress , acting perpendicularly and parallel to a plane respectively. Compressive stress is measured in pascals (Pa) or kilobars (kb).

Article: tensile stress
A Dictionary of Earth Sciences;      37 words ...tensile stress A normal stress (negative compressive stress) which pulls apart the material on either side of a plane. Tensile stress greatly weakens rocks, reducing the amount of shear stress that is needed to produce failure in them.
