Analysis of structural or mechanical failure is the organised approach to discovering the reason behind a breakdown in a part, system, or material. These breakdowns are usually linked to incorrect loading or conditions during use. Specialists use technical assessments to examine what failed, when it failed, and why, in order to prevent similar issues from reoccurring.
Understanding Technical Investigations
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 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
- 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
- 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 material use that reduce cost and improve safety.
Benefits for Organisations
These investigations help stop repeat incidents, 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?
When a system stops functioning as expected, shows signs of damage, or poses a safety concern.
Which professionals handle analysis?
Typically, a combination of lab technicians and engineering consultants.
Which instruments are used?
Common tools include SEM, tensile test machines, and visual inspection instruments.
How long does a typical case take?
Some investigations wrap up within days; others involve weeks of review.
What’s the end result?
Evidence-based reporting, useful for technical teams, insurers, and legal review.
