Definitions for "Creep Strength"
(1) The constant nominal stress that will cause a specified quantity of creep in a given time at constant temperature; (2) the constant nominal stress that will cause a specified creep rate at constant temperature.
The constant nominal stress that will cause a specified quantity of creep or secondary creep in a given time at a constant temperature. The resulting rate of continuous deformation is often expressed as PSI to produce 0.1 percent elongation in 10,000 hours at the temperature indicated.
Maximum stress required to cause a specified amount of creep in a specified time. Also used to describe maximum stress that can be generated in a material at constant temperature under which creep rate decreases with time. An alternate term is creep limit
