creep




In metallurgy, the continuing deformation of a metal under stress so that it appears to flow like an extremely viscous liquid. Metal components can be tested for creep rate – the percentage elongation per 1,000 hours at a particular temperature. Engineers have to consider both the applied stress and the temperature of metal structures to avoid possible failure through creep.
