Compressive strength of rocks - PetroWiki

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but …

Compressive strength - Wikipedia

In mechanics, compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size (as opposed to tensile strength which withstands loads tending to elongate). In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart).

A material's maximum capacity to elastically absorb energy is then the total area under the stress-strain curve's linear elastic regime: U el max = σ yε y (5) Where σ y and ε y are the yield stress and yield strain at which linear elastic behavior ceases. At larger strains, material deformation becomes irrecoverable and non-linear, or ...
