Stress Rupture and Creep Test Methods

Critical to understanding and preventing product failures, stress rupture and creep test methods provide valuable insights into the effect of long term stress on materials. Element performs standard and elevated test methods for a variety of materials, including metals, composites and plastics.

Stress rupture testing and creep tests are specialized mechanical testing services that provide manufacturers with critical data about their product's performance over time. During testing, a material is held under a definite constant load for a given period of time, at up to 1800°F, until failure occurs. Our experts then analyze the results to provide important data about physical and thermal stress over extended periods.

Our Stress Rupture and Creep Test Services

With accreditation including ISO and Nadcap, Element is committed to providing the highest quality stress rupture and creep test services to clients across many sectors. Our stress rupture testing and creep testing laboratories are continuously growing to meet the needs created by new and advanced materials. Element laboratories are also fully supported by experienced in-house machine shops that provide precise specimen preparation and fixture fabrication on all specimen and material types.

What is Stress Rupture?

Our stress rupture services test for total, catastrophic failure of materials under load.

More Less

Stress rupture is the sudden and complete failure of a material under stress. During testing, the sample is held at a specific load level and temperature for a pre-determined amount of time. In stress rupture testing, loads may be applied by tensile bending, flexural, biaxial or hydrostatic methods.

What is Creep Testing?

Measuring load over an extended period of time, creep test programs use continuous load and elevated temperature to test for eventual material failure.

More Less

Creep is the time-dependent deformation of a material while under an applied load below its yield strength. Creep testing is most common at elevated temperature, but some materials will exhibit creep at room temperature. Unless stopped, creep testing terminates in rupture.
