Technical examination of failures involves identifying the cause behind a breakdown in a component. Failures are not usually random. They are typically caused by design mistakes or defects. By using analytical tools, investigators can work out what failed and why, and then make recommendations to stop it happening again.
Why Technical Investigations Are Carried Out
An investigation helps understand how a structure or part responded under specific conditions. These investigations support a wide range of sectors such as construction, energy, and transport. They rely on a combination of physical evidence, lab analysis, and data reviews to come to a conclusion based on measurable facts.
Stages of a Failure Investigation
- Review background data, design files, and operational logs
- Conduct a detailed visual inspection for surface cracks or signs of stress
- Carry out deeper analysis using SEM or material profiling
- Perform tests to confirm or rule out chemical or mechanical defects
- Interpret findings using design and stress calculations
- Summarise all findings and produce a report with suggested actions
Common Applications in the Field
Failure analysis supports industries such as manufacturing, rail, and infrastructure. For example, if a bolt shears or a weld fails, engineers may carry out chemical testing or stress analysis to determine the cause. These findings are used to guide repairs and can reduce both cost and operational disruption.
How Businesses Benefit from Failure Analysis
Organisations use failure investigations to reduce disruptions, avoid repeated faults, and support insurance or legal documentation. Feedback from these reviews also guides engineering decisions. Over time, this leads to more predictable performance and improved asset life.
