Forensic/ Expert Witness Services

Engineering Expert Witness

Engineering Expert Witness Services
Our team at O’Donnell Consulting provides expert witness services, litigation support, and forensic engineering – investigating product liability, structural failures, construction issues, industrial accidents, fire/explosions on a range of equipment including chemical, industrial, construction, electrical, transportation, and energy applications.

We have supported legal firms in State, Federal & International Courts (on both Plaintiff and Defendant cases) as well as insurance companies – from simple to complex technical issues.

Our experience includes:

Coke Oven Battery Analysis Results

We were asked to provide technical expertise in a ($200 M) construction litigation regarding the structural integrity of a coke oven battery. Finite element analysis was used to calculate temperatures, deflections, strains, and stresses to evaluate the long term integrity of the roof and heating walls. The results showed that the battery oven walls would not deflect enough to induce instability. The construction imperfections had no meaningful effect on the structural integrity, robustness, or longevity of the battery.

To see more of the engineering and legal projects we have worked on, see Portfolio.

With a knowledge of materials, metallurgy, fabrication practices and codes and standards, we determine how materials and products fail, including mechanical integrity of equipment that has deteriorated due to corrosion, fatigue, damage, exposure to fire, abuse, or improper manufacture. For over 40 years, we have been performing engineering design & analysis, troubleshooting and expert witness testimony - providing quantitative results and effective visuals/ animations. These results:

  • Are based on accurate engineering models
  • Clarify the root cause
  • Enables judges and juries to easily understand the technical issues

In a Range of Applications:
Consumer: Walkways, Appliances, Electrical Equipment, Sporting Equipment, Furnaces
Construction: Roofs, Scaffolds, Demolition and Construction Equipment, Welded Connections, Coatings
Industrial: Plants, Pressure Vessels, Pipes, Pumps, Ductwork, Valves
Oil/Gas: Pumps, Pipelines, Compressors, Dryers, Separators
Chemical: Reactors, Structures, Pressure Vessels, Heat Exchangers
Vehicles: Steering Mechanisms, Suspensions, Fifth Wheels

Engineering principles hold true, whether in the design of sporting goods, industrial equipment, or aeronautical structures. If you do not see the equipment you wish to investigate listed in the various industries we have supported, please give us a call. We may be able to assist.

Metallurgy/ Testing
We offer a full spectrum of metallurgical testing in conjunction with our engineering analysis tools to evaluate the root cause of component failure. Our testing includes:

  • Chemical and mechanical analyses
  • Metallographic examination
  • Material testing
  • Corrosion testing
  • Electron beam microscopy

Biomechanical Engineering

  • Accident Reconstruction
  • Vehicle Dynamic Analysis
  • Injury Biomechanics
  • Occupant Dynamics
  • Human Factors
  • Product Safety

Producing Results
The right expert can offer a powerful advantage during litigation - what sets us apart is our multi-disciplinary experience in engineering design, analysis and troubleshooting. When performing forensic analysis, we thoroughly investigate the issues - from taking data at the scene, to analyzing drawings, material specifications, and supporting documentation.

Our investigations range from the simple to complex. Quite often Finite Element Analysis (FEA) is used to evaluate design, materials and fabrication/ construction defects. These models produce accurate results (images or animations) which are used to help judges and juries understand the technical issues. (O'Donnell was one of the first engineering firms to use FEA in the Courtroom.)

In addition to determining the root cause of technical issues - we also provide engineering support to resolve them. See Engineering Troubleshooting.

We have worked in State, Federal and International Courts - including Canada, Mexico, South America, UK, Spain, and the Virgin Islands. See our list of Clients.
