Engineering failure analysis is the step-based approach to discovering the explanation behind a breakdown in a part, system, or material. These breakdowns are usually linked to material issues or environmental exposure. Specialists use technical assessments 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 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
- Identify any marks, corrosion, or impact evidence through inspection
- Examine the microstructure using tools such as SEM or optical scopes
- 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 design practices that reduce cost and improve safety.
Reasons Businesses Conduct Technical Reviews
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
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.
How long does a typical case take?
Some investigations wrap up within days; others involve weeks of review.
What do reports include?
Documentation outlining what failed, how it failed, and suggested changes.
Final Insight
Engineering failure analysis helps improve future performance by understanding what caused past issues.
