Analysis of structural or mechanical failure is the organised approach to discovering the source behind a breakdown in a part, system, or material. These breakdowns are usually linked to design error or conditions during use. Specialists use tested methods to examine what failed, when it failed, and why, in order to prevent similar issues from reoccurring.
The Function of Engineering Investigations
An investigation aims to establish the behaviour of a component 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 fact-based reporting that can support future engineering decisions.
Steps in the Analysis Process
- Gather historical data, technical records, and environmental details
- Look for visual signs of damage or irregular use
- Use detailed imaging or micro-level analysis to assess internal structure
- Evaluate tensile properties, contamination, or stress profiles
- Match test outcomes with the expected load path and material limits
- Write a report detailing findings and improvement suggestions

Where Failure Analysis Is Used
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 design practices that reduce cost and improve safety.
How Failure Analysis Supports Operations
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 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
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.
What equipment helps with analysis?
Microscopes, spectrometers, modelling software, and force measurement tools may be used.
What is the usual time requirement?
Some investigations wrap up within days; others involve weeks of review.
What’s the end result?
A full breakdown of findings, including images, graphs, and clear recommendations.
