Does creep occur at high temperatures?
At elevated temperatures and stresses, much less than the high-temperature yield stress, metals undergo permanent plastic deformation called creep.
Can creep occurs at low temperature?
Creep at low temperature can be understood as time-dependent plasticity that occurs at T < 0.3Tm and at stresses often below the macroscopic yield stress (σy0.002). This is where creep is often not expected.
How does creep vary with temperature?
As the temperature increases and the creep time increases, the average creep modulus of similar materials in soft rock decreases. As the axial pressure increases, the creep strain deformation increases continuously, and the larger the axial pressure, the more significant the creep strain changes.
