Identifying engineering faults is the step-based approach to discovering the source behind a breakdown in a part, system, or material. These breakdowns are usually linked to incorrect loading or external factors. Specialists use technical assessments to examine what failed, when it failed, and why, in order to prevent similar issues from reoccurring.
Understanding Technical Investigations
An investigation aims to understand the material’s response under specific loads, settings, or environments. It is used across many fields where system reliability is essential. Investigators collect facts, inspect the failed parts, and examine the data in context with design expectations. This approach enables fact-based reporting that can support future engineering decisions.
Sequence of a Failure Examination
- Compile background information such as performance logs and installation records
- Inspect the component visually to find wear patterns, cracks, or misalignment
- Examine the microstructure using tools such as SEM or optical scopes
- Confirm or dismiss material defects using chemical or mechanical testing
- Interpret the physical findings using stress and failure theories
- Deliver a final assessment outlining corrective steps and preventive measures

Industry Areas Benefiting from Failure Analysis
Failure reviews are carried out in sectors such as power systems, marine structures, and public infrastructure. For example, a fractured pipe may require fracture surface analysis, or a collapsed beam may need calculations based on loading conditions. The analysis doesn’t only guide repair—it often leads to updates in inspection schedules that reduce cost and improve safety.
Benefits for Organisations
These investigations minimise the risk of future faults, support insurance claims, and contribute to better engineering decisions. They also support compliance with standards and provide defensible reports useful in claims or audits. Most importantly, they allow engineering teams to adjust system designs based on real-world data.
Frequently Asked Questions
Why do faults get investigated?
Triggered by breakdowns, performance loss, or unexpected behaviour.
Who runs the investigation?
Experienced engineers in materials, design, or structural testing lead the process.
Which instruments are used?
Common tools include SEM, tensile test machines, and visual inspection instruments.
What is the usual time requirement?
Cases vary, but detailed lab testing or external inspections can extend the timeline.
What’s the end result?
A full breakdown of findings, including images, graphs, and clear recommendations.
Final Insight
