Creep

Creep is defined as a time-dependent deformation of a material while under an applied load. It is usually regarded as an elevated temperature phenomenon, although some materials creep at room temperature. If permitted to continue indefinitely, creep may terminate in rupture. Creep in service is usually typified by complex conditions of loading and temperature.

Creep

Creep is the time-dependent deformation of materials that occurs at temperatures greater than about 40 % to 50 % of the lowest melting point or lowest end of the melting range.
