What is Residual Stress Testing at Element?

Residual stress occurs when materials retain internal stresses from manufacturing processes like fabrication, heat treatment, or welding. Excessive residual stress can lead to deformation, cracking, and premature failure, especially in load-bearing components. At Element, we measure these stresses using multiple advanced techniques to determine material safety and prevent failures. Our comprehensive testing helps ensure your materials remain fit for purpose throughout their lifecycle.

What can Element offer you for residual stress measurement?

Key tests offered

We offer several tests for residual stress measurement, helping to ensure that the materials used in aerospace, construction, transportation, and other critical industries are safe and fit for purpose:

Strain Gaging (ASTM E837 - Hole-Drilling Method) - Industry-standard technique to measure near-surface residual stresses using strain gages.
X-Ray Diffraction (XRD) Analysis - A precise method to assess subsurface stress by analyzing atomic lattice spacing changes in crystalline materials.
Barkhausen Noise Analysis (American Stress Tech Microscan) - A non-destructive technique for assessing residual stress in ferro-magnetic materials, ideal for components affected by grinding or machining.
Custom Combined Testing Programs - Tailored multi-method approaches for complex materials or failure analysis.
On-Site and Laboratory Testing - Flexible service delivery to accommodate both in-field and controlled lab environments.

Frequently asked questions

What causes residual stress in materials?

Residual stress can be caused by fabrication errors, heat treatment, welding, and processing operations such as milling, annealing, or machining.

When is residual stress measurement necessary?

Residual stress measurement is critical when you need to determine if materials are still safe for use, particularly after manufacturing processes or when external stresses are present. It's essential when stress levels may be approaching a material's yield strength.

Can multiple testing methods be combined for better results?

Yes. For complex failures or unique material requirements, our experts can create customized testing programs that combine multiple techniques, ensuring the most accurate stress analysis.
