Creep and Stress Rupture Testing

Creep and Stress Rupture Tests are conducted at temperatures up to +1200°C

The Creep and Stress Rupture Testing lab at Westmoreland Mechanical Testing & Research has the capability to perform a variety of tests, such as: Creep Rupture, Stress Rupture, Cyclic Rupture, Static Notch and Embrittlement Relief.

Cyclic Rupture Testing is designed to load and unload a test sample at certain time intervals. The test temperatures range from room temperature to +2200°F. Prior to starting a test, four strain gages are attached to the test specimen to insure that bending strains are within specification requirements.

The Static Notch Test is performed at room temperature under a constant load for a minimum of 5 hours to determine if the material is notch sensitive at room temperature.

The Embrittlement Relief Test is also performed at room temperature, but for 200 hours under a load of some percentage of either the yield strength or ultimate tensile strength. Typically, this test is conducted in accordance with ASTM F 519 at 75% of the yield strength to determine if the material is susceptible to hydrogen embrittlement.
