Forensic engineering is the application of scientific and engineering principles to settle disputes between two or more parties. These disputes typically arise when a product or structure fails to perform as expected and causes a loss to one of the parties. Forensic engineering is practiced for insurance companies evaluating claims for payment or subrogation and for attorneys pleading or defending product liability law suits. Engineering evaluation determines the cause or causes of the failure to help assign liability for the damages.Most failures involve materials damage of some sort to the materials comprising the failed component(s). Therefore, materials engineering is often an integral aspect of forensic engineering investigations. Evaluation of the material’s behavior using standard failure analysis practices typically identifies the failure mechanism, and this information, on its own or in combination with other engineering evaluations, leads to determination of the root cause and liability. While our expertise is focused on materials engineering, MEE routinely collaborates with experienced investigators, engineers, and scientists in other disciplines as needed for complex investigations.
