Identifying engineering faults is the methodical approach to discovering the reason behind a breakdown in a part, system, or material. These breakdowns are usually linked to design error or external factors. 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 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 accurate conclusions 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
- Carry out metallurgical testing to examine grain boundaries or defects
- Perform hardness checks and compositional assessments
- Apply engineering models and calculations to link evidence to root cause
- Deliver a final assessment outlining corrective steps and preventive measures

Where Failure Analysis Is Used
Failure reviews are carried out in sectors such as heavy machinery, fabrication, and bridge construction. 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.
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 improve part selection based on real-world data.
Frequently Asked Questions

Requested when the failure could impact safety, cost, or future reliability.
Who runs the investigation?
Typically, a combination of lab technicians and engineering consultants.
Which instruments are used?
Microscopes, spectrometers, modelling software, and force measurement tools may be used.
Is the duration fixed?
Some investigations wrap up within days; others involve weeks of review.
What happens after analysis is complete?
A full breakdown of findings, including images, graphs, and clear recommendations.
Final Insight
It provides solid evidence to refine designs and prevent system failure.
