What is Failure Analysis and Investigation?

If your products or components have failed, it’s important to understand why. Without proper investigation, the same issues could happen again. Not only is it costly to keep replacing products and components, but it can also risk the productivity and safety of your operations.  

Failure Investigation helps to identify the root cause and nature of failure. Metal fatigue failure can happen for many reasons:

  • Design flaws 
  • Material defects 
  • Operational stresses 
  • Heat treatment processes 
  • Misapplication of the component 

As a trusted advisor, our team combines deep technical knowledge and advanced product Failure Testing to deliver clear, actionable insights you can trust.

Whether you’re facing a production setback, quality issue, or safety concern, we’re here to assist you. We’ll work with you to identify underlying factors contributing to failure and help you implement effective solutions.

How we'll work with you

Failure Analysis is crucial for understanding why machines, components or raw materials fail, particularly in cases of injury or legal dispute. 

As a fully independent laboratory, we conduct in-depth Failure Investigations for you and your customers. We trace failures back to their root cause, helping you enhance safety and reliability. Our findings can support quality control, compliance reviews, and even legal cases if required.

 

How to prepare for a Failure Investigation  

To get started with our services, we’ll first need to understand the situation of the failure. We’ll ask for some details about the operational and environmental conditions, such as:

  • History of your part or component 
  • Material type and specifications (if known) 
  • Processing technique 
  • Service conditions (temperature, pressure, humidity) 
  • Any exposure to chemicals or corrosive environments 
  • Events leading up to the failure  

We’ll then begin our Failure Investigations once we receive a sufficient sample or part of the component.

Why is Failure Analysis & Investigation important?

Understanding the mechanisms behind metal failures is key to improving your product design, material selection, and maintenance strategies. This leads to better safety practices, reliability, and cost-efficiency.  

Common failures we have investigated:
  • Metal fatigue: Repeated stress causing cracks and fractures in weak points like sharp corners or weld joints 
  • Corrosion failures: Exposure to harsh environments which weakens metals and leads to premature cracks 
  • Stress-related cracks: Components that have exceeded their strength limits, results in metal deformation 
  • Hydrogen damage: Internal weakening of metals due to hydrogen exposure 

We investigate failure on a variety of components like bolts, welds, pipework, machinery, metal structures, or consumer products, to prevent future breakdowns and enhance performance.

Frequently asked questions

What do Failure Analysis Reports include?

Our clear explanations ensure you can fully understand the results and know what action to take. We can also help you implement recommendations, so you have reliable solutions in place to avoid future failures. 

How long does Failure Analysis take?

The duration of a Failure Analysis varies depending on your needs. We’ll consider the complexity of the failure, resource availability, and extent of testing when organising your Failure Analysis. Not all investigations require full testing processes, so some can be completed within a few days. Others may take several weeks or months if they require more thorough investigations.  

Once we’ve gathered all the information, our experts can tell you how long the investigation is likely to take. As always, we’ll aim to carry out our investigations with as little disruption to your operations as possible. To arrange expert Failure Analysis, get in touch with our team. 

What happens if I don’t conduct a Failure Investigation?

If a Failure Investigation is not conducted after the failure of a product or component, several critical issues may arise: 

  1. Non-compliance to standards: Without a thorough investigation, it’s difficult to know whether a product or component meets international standards, which could raise concerns about its quality and safety. 
  2. Legal implications: If the failure results in accidents, you could face lawsuits. Not investigating the failure could result in non-compliance with regulatory requirements and leave you at risk of lawsuits or fines. 
  3. Risk to other products: The root cause of the failure might be applicable to similar products or components. Without investigating, other products with the same issue may also fail, potentially causing further problems and increasing the risk to safety. 

Failure Investigations help mitigate these risks by identifying the underlying issues, ensuring compliance with standards, and preventing future failures. 

Can Failure Analysis be used for legal or insurance purposes?

Yes, Failure Analysis can be used for legal or insurance purposes, especially in cases involving product liability, property damage, or personal injury claims. Failure Analysis can help provide supportive documents and evidence for your claim. If needed, our experts can provide testimony and evidence in legal proceedings to help with litigation or material failure claims. 

What is fatigue failure in metals?

Fatigue failure in metals occurs when a material repeatedly experiences fluctuating stresses. This can create cracks that gradually grow until the metal breaks. Failure Analysis helps identify fatigue failure by examining the fracture surface for fatigue features. It also involves assessing the metal’s stress history and pinpointing underlying issues such as design flaws or manufacturing defects. This thorough examination helps diagnose the problem, prevent future failures, and enhance component reliability. 

What sectors benefit from Failure Investigations?

Failure Analysis is crucial across various industries to enhance safety, reliability and cost efficiency. Some key industries that use our services include: 

  • Manufacturing 
  • Construction & Infrastructure 
  • Oil & Gas 
  • Aerospace 
  • Automotive & Transportation 
  • Power Generation
