Structural integrity is the measure of a component’s ability to hold together without breaking or deforming.
Ensuring structural integrity is critically important for pipeline operators, automakers, oil and gas companies, ship builders, and manufacturers of industrial machinery.
We know it’s not just a matter of strength testing and weld failure analysis – it’s about developing the most trustworthy methods for determining material properties, predicting damage in advance of application, and having the expertise to interpret and analyze results with accuracy and precision.
Since the founding of EWI, we have leveraged our extensive welding, materials, and finite-element-analysis capabilities to deliver comprehensive structural integrity assessments. These assessments – based on material testing, design analysis, fabrication methods and loading conditions – enable our clients to push the envelope in materials performance. Our structural integrity expertise includes:
- Material preproduction qualification testing for offshore oil and gas infrastructure
- General fracture toughness and fatigue analysis of welded joints
- CTOD, J, R-curve, fatigue crack growth rate,fatigue life characterization (S-N curves)
- Time-dependent fracture tests (step-wise incremental loading, sustained load cracking, etc.)
- Development of spot weld failure parameters for full-vehicle crash modeling
