Analysis of structural or mechanical failure is the methodical 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 scientific approaches to examine what failed, when it failed, and why, in order to prevent similar issues from reoccurring.
Understanding Technical Investigations
An investigation aims to establish the behaviour of a component under specific loads, settings, or environments. It is used across sectors including energy, infrastructure, and transport. Investigators collect measurements, 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
- Identify any marks, corrosion, or impact evidence through inspection
- Use detailed imaging or micro-level analysis to assess internal structure
- Confirm or dismiss material defects using chemical or mechanical testing
- Apply engineering models and calculations to link evidence to root cause
- Write a report detailing findings and improvement suggestions

Where Failure Analysis Is Used
Failure reviews are carried out in sectors such as aerospace, nuclear, automotive, and rail. 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, limit equipment downtime, 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 improve part selection based on real-world data.
