Sentence examples for exceeds the rock from inspiring English sources

BO occurs when σ tmax exceeds the rock mass strength.

Compressive failure is attributed to wellbore breakouts which happen when the wellbore stress exceeds the rock compressive strength.

Breakouts form only at azimuths around the borehole where local differential stress at the borehole wall exceeds the rock's failure criterion (Fig. 2a) (Zoback 2007).

The redistributed stress state may exceed the rock strength and hence, failure can occur.

Compressional breakouts (BO) form where differential stresses at the borehole wall exceed the rock strength.

Tensile failure occurs when the excessive mud pressure increases tensile stresses to magnitudes exceeding the rock tensile strength.

Hydraulic fracturing in rocks takes place when the fluid pressure within the rock exceeds the smallest principal stress plus the tensile strength of the rock.

When the circumferential stress acting around a wellbore exceeds the compressive strength of the rock in a vertical well, conjugate shear fractures form at the wellbore wall centred on the minimum horizontal stress direction, causing the rock to spall off (Bell 1979).

Columnar jointing occurs when the thermal stress exceeds the yield strength of the rock; thus, we simply assumed that joints occur instantaneously when the temperature falls below the glass transition temperature, which is assumed here to be 900 °C (Peck and Minakami, 1968).

Besides, loading damage produces when the inner stress exceeds the bearing capacity of rock.

It is worth noting that the imbibed volume exceeds the pore volume in rocks, so the water presumably entered into a space where the gas used to measure the porosity could not enter.
