Identifying engineering faults is the organised approach to discovering the source behind a breakdown in a part, system, or material. These breakdowns are usually linked to material issues or conditions during use. Specialists use scientific approaches 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 review failure mechanisms under specific loads, settings, or environments. It is used across industries that rely on high safety standards. Investigators collect observations, 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
- Gather historical data, technical records, and environmental details
- Look for visual signs of damage or irregular use
- Examine the microstructure using tools such as SEM or optical scopes
- Evaluate tensile properties, contamination, or stress profiles
- Match test outcomes with the expected load path and material limits
- 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 material use that reduce cost and improve safety.
How Failure Analysis Supports Operations
These investigations minimise the risk of future faults, strengthen health and safety records, and contribute to better engineering decisions. They also support compliance with standards and provide verifiable evidence useful in claims or audits. Most importantly, they allow engineering teams to improve part selection based on real-world data.
Frequently Asked Questions

Typically, a combination of lab technicians and engineering consultants.
Which instruments are used?
Common tools include SEM, tensile test machines, and visual inspection instruments.
Is the duration fixed?
The duration depends on how complex the failure is. It could take a few days or a few weeks.
What do reports include?
Documentation outlining what failed, how it failed, and suggested changes.
