Dynamics Expert Witnesses
Engineering dynamics becomes the focus of litigation when moving, vibrating, or rotating systems fail to behave as designed. Excessive vibration in turbines, compressors, and pumps, resonance in structures and pipelines, fatigue cracking in wind turbine and aerospace components, and unexpected motion in industrial machinery can halt production and lead to costly repairs. The resulting disputes between owners, equipment manufacturers, engineering firms, and insurers often concern whether dynamic loads were properly anticipated in design, whether installation altered the system's behavior, or whether operation outside specified conditions caused the damage. Those questions are difficult because dynamic behavior depends on subtle interactions among stiffness, mass, damping, and excitation that are seldom obvious from a failed part alone.
A dynamics expert helps attorneys determine why a system responded the way it did and whose decisions made that response possible. Typical work includes modal and finite element analysis, review of vibration monitoring data and spectra, rotordynamic modeling, and field or laboratory testing to identify natural frequencies and forcing sources. The expert can compare the design against applicable codes and industry standards, such as API standards for rotating equipment and ASME guidance, and determine whether a resonance, imbalance, misalignment, or foundation issue initiated the failure. Those findings establish causation, support allocation of responsibility among designers, suppliers, and operators, and provide the technical foundation for repair and business interruption damages.
The most effective dynamics experts have diagnosed vibration problems in the field as well as modeled them on a computer. Round Table Group can introduce mechanical and structural engineers, rotordynamics specialists, and academics in vibration and structural dynamics, including professionals whose careers have involved organizations such as NASA, Sandia National Laboratories, General Electric, and Boeing. That practical experience allows an expert to explain to a fact-finder why a seemingly minor design or installation choice could produce a major failure. Drawing on more than 75,000 expert searches for litigators, we can match the equipment, loading conditions, and failure mode in your case with the right specialist, and we invite you to begin by calling us at (202) 908-4500.
