Examples of Engineering Expert Witness Cases

Engineering Expert Witness Services

We provide expert witness services, litigation support, and forensic engineering – investigating product liability, structural failures, construction issues, fire/explosions, industrial and other accidents on a range of equipment including chemical, industrial, construction, electrical, transportation, and energy applications.

For over 40 years, 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:

Finite Element Results on Coke Oven Battery

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.

  • Recent Projects

  • Experience

    With a knowledge of materials, metallurgy, fabrication practices, finite element analysis, 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

    Materials and engineering principles hold true across many applications – including energy, mining, manufacturing, aerospace and petrochemicals. To see the various types of problems we’ve solved – see our Portfolio.

    If you don’t see your application listed in the various industries we’ve supported, please give us a call. We may be able to assist – if not, we may be able to refer you.

    Examples Include:

    • Consumer
    • Commercial
    • Petrochemical
    • Manufacturing
    • Energy
    • Appliances
    • Sporting Equipment
    • Furnaces
    • Assemblies
    • Conveyors

    Weld/ Materials Expert Witness

    Litigation involving welding typically involves product defects/failure or safety-related incidents. Our expert witness services offer a full spectrum of testing in conjunction with engineering analysis tools to evaluate the root cause of failure. These investigations include:

    • Weld/ Materials Testing
    • Metallurgical Examination & Testing
    • Chemical and Mechanical Analyses
    • Corrosion Testing
    • Electron Beam Microscopy

    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, materials 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. Finite Element Analysis has been qualified for use in the aerospace, marine and defense industries – and has passed the Daubert Challenge. FEA models and animations produce accurate results which are used to help judges and juries understand the technical issues. In addition to determining the root cause of technical issues – we also provide engineering support to resolve them.

    Learn from the experience of others. Especially when one such “other” is Dr. William O’Donnell, PhD, PE, Founder and President of O’Donnell Consulting Engineers, Inc., and ASME “Engineer of the Year” – his 50 years of experience in analysis of components including fatigue and fracture safety evaluations and failure analyses are now comprised in this volume.
