Creep - ASTM D2990
Creep is the permanent deformation resulting from prolonged application of stress below the elastic limit. Creep is influenced by the magnitude of the load, the time the load is applied, and the temperature.
Testing consists of applying a load to a test specimen and measuring the strain after a specified time.
The strain produced by a specified tensile load after a specified time of application.
Tensile Creep Test
The outer fiber strain produced by a specified flexural load after a specified time of application.
