compresive stress of live rock

Stress (mechanics) Simple English Wikipedia, the free ...

Tensile stress is the opposite of compressive stress. Structural members in direct tension are ropes, soil anchors and nails, bolts, etc. Beams subjected to bending moments may include tensile stress as well as compressive stress and/or shear stress. Tensile stress may be increased until the reach of tensile strength, namely the limit state of stress.

What is Tensile Strength? Definition from Corrosionpedia

The tensile strength of a material is the maximum amount of tensile stress that it can take before failure, such as breaking or permanent deformation. Tensile strength specifies the point when a material goes from elastic to plastic deformation. It is expressed as the minimum tensile stress (force per unit area) needed to split the material apart.

Particle density, an average mass per unit volume of the solid particles in a rock sample, is usually determined by applying the pycnometer method (Head, 1992). Permeability and porosity depend on pores in the rock. There are two discerned typologies of pores in rocks: closed and open pores.

Deformation of Rock

If stress is not equal from all directions then we say that the stress is a differential stress. Three kinds of differential stress occur. Tensional stress (or extensional stress), which stretches rock; Compressional stress, which squeezes rock; and ; Shear stress, which result in slippage and translation.
