Creep testing is conducted using a tensile specimen to which a constant stress is applied at a constant temperature, often by the simple method of suspending weights from it. The test is recorded on a graph of strain versus time. The use of metals at high temperatures introduces the possibility of failure in service by a mechanism known as creep.
