Stress Rupture and Creep Testing

Stress Rupture and Creep Testing mean safer products
The ability to safely and consistently hold a load for many, many performance hours is a critical characteristic for parts and products supplied to aerospace, aviation, defense, automotive, nuclear energy, wind power, marine, and other industries.

Stork's expert engineering staff and testing laboratories hold the rigorous approvals necessary to offer stress rupture and creep testing to designers, manufacturers, and buyers of quality critical parts such as fasteners. Stork knows how to help you meet your standards and your objectives.

What happens in Stress Rupture?
Stress Rupture is the sudden and complete failure of a material held under a definite constant load for a given period of time at a specific temperature. Loads may be applied by tensile bending, flexural, biaxial or hydrostatic methods.

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

Stress Rupture and Creep testing are specialized services that provide manufacturers with critical data about their product's performance. Stork experts test your sample under a definite constant load for a given period of time and at a specified temperature, until failure. Loads may be applied by tensile bending, flexural, biaxial or hydrostatic methods, as needed. Stork conducts Stress Rupture and Creep testing on a wide variety of materials to both standard and customized specifications.

Capacity and capabilities
Stork applies Six Sigma and Lean principles and methods to operate our highly productive laboratories and provide cost-effective and accurate testing programs. We work with our customers to create customized and efficient schedules that meet their volume and turnaround needs.
