Engineering failure analysis is the organised approach to discovering the reason behind a breakdown in a part, system, or material. These breakdowns are usually linked to material issues or external factors. Specialists use tested methods to examine what failed, when it failed, and why, in order to prevent similar issues from reoccurring.
Why Failure Reviews Are Necessary
An investigation aims to understand the material’s response under specific loads, settings, or environments. It is used across sectors including energy, infrastructure, and transport. Investigators collect facts, inspect the failed parts, and examine the data in context with design expectations. This approach enables technical insight that can support future engineering decisions.
Sequence of a Failure Examination
- Start with collecting all available technical documentation, including drawings and use history
- Inspect the component visually to find wear patterns, cracks, or misalignment
- Use detailed imaging or micro-level analysis to assess internal structure
- Evaluate tensile properties, contamination, or stress profiles
- Interpret the physical findings using stress and failure theories
- Report the failure cause, contributing factors, and recommendations for changes

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.
How Failure Analysis Supports Operations
These investigations cut the chance of reoccurrence, strengthen health and safety records, and contribute to better engineering decisions. They also support compliance with standards and provide technical records useful in claims or audits. Most importantly, they allow engineering teams to adjust system designs based on real-world data.
Frequently Asked Questions
What usually prompts failure analysis?
When a system stops functioning as expected, shows signs of damage, or poses a safety concern.
Who performs the work?
Experienced engineers in materials, design, or structural testing lead the process.
Which instruments are used?
Depending on the failure type, digital and physical tools are used for measurement and simulation.
Is the duration fixed?
Cases vary, but detailed lab testing or external inspections can extend the timeline.
What do reports include?
Evidence-based reporting, useful for technical teams, insurers, and legal review.
