Forensic Engineering Process

Here are the steps we carry out during our investigations

1. Defining the Problem:

At Brooks Forensic Engineering, we begin by meticulously defining the specific issue or failure requiring investigation, whether it involves failure, degradation, or structural collapse. Clear articulation of the problem serves as the foundation for our comprehensive analysis and ensures a focused investigative approach.

2. Gathering Information:

We delve into the case by gathering all relevant data, including design specifications, service conditions, inspection reports, maintenance records, repair and re-work, and any other pertinent information related to the investigation. Our meticulous approach to data collection provides us with a comprehensive understanding of the situation, enabling a thorough and informed investigation. Our experience also allows the engineers to discuss relevant processes and get a better understanding.

3. Collecting Evidence:

4. Visual Inspection:

Our experts conduct thorough visual inspections of the failed components and their surrounding areas. We keenly observe visible signs of damage, fractures, corrosion, deformation, or any other abnormalities. Visual inspection serves as an essential initial step in understanding the extent of the failure and guides subsequent investigative efforts.

5. Non-Destructive Testing (NDT):

Utilising NDT methods, including ultrasonic testing, radiography, magnetic particle testing, and dye penetrant testing, we assess the integrity of materials without causing further damage. NDT techniques provide valuable insights into the internal structures without destruction of the parts, allowing us to identify defects and assess the overall integrity of the components under investigation.

6. Laboratory Testing:

We gather information regarding the part’s history, including material type and specification, processing technique, service conditions, and events preceding the failure. From there, the sample or part will go through the failure investigation process outlined below at the failure analysis lab.

Preliminary visual examination to reveal any defects, fractures or corrosion
EDX microanalysis, performed using a facility on our Scanning Electron Microscope (SEM)
Scanning electron microscope examination to establish fracture mechanisms
Metallographic examination to determine microstructural features, such as phases present, heat treatment condition and internal material flaws
Impact testing
Hardness testing
Tensile testing
Chemical analysis to check the sample meets compositional requirements
Lastly, the results will be analysed and reported

7. Finite Element Analysis (FEA):

Our utilisation of Finite Element Analysis (FEA) simulations allows us to model the conditions and stresses encountered by the structure or weld. This advanced computational analysis assists in identifying vulnerabilities.

8. Expert Consultation:

We collaborate closely with specialists. Seeking expert consultation ensures a multidisciplinary approach to our investigations. By integrating diverse expertise, we gain valuable insights, enabling a more comprehensive analysis of the failure mechanisms.

9. Root Cause Analysis:

Our dedicated team conducts in-depth root cause analysis, delving into the failure’s immediate and contributing causes. Through meticulous tracing, we identify the primary factor initiating the failure – the root cause. This comprehensive analysis is integral to our investigative process, offering a clear understanding of the underlying issues.

10. Forensic Engineering:

We merge our engineering expertise with investigative techniques, forming the core of forensic engineering. Our approach involves applying scientific principles and engineering knowledge to analyse failures, accidents, or defects in materials and structures. We conduct forensic engineering assessments, particularly in legal or insurance contexts, to determine the root causes of failures with precision.

11. Report and Recommendations:

Following our rigorous investigation, we document our findings, including the identified root cause / causes, in a comprehensive report. This report not only outlines the investigative process but also provides detailed recommendations for corrective actions. These recommendations may encompass material improvements, process changes, design modifications, or alterations in inspection and maintenance procedures. Our goal is to offer actionable insights that enhance the integrity and reliability of welds, materials, and structures, ensuring the prevention of similar incidents in the future.
