Founder

Duffner Engineering specializes in the practice of failure analysis. Our engineers have backgrounds in mechanical engineering, materials science, and metallurgy. We focus on determining the root cause of failures in a wide variety of products, including machinery, vehicles, pressure vessels, medical devices, consumer products, building materials, and communications equipment. Our practice conducts construction defect investigations of plumbing and heating, ventilating, and air conditioning installations. Our specific areas of expertise are fatigue, fracture and corrosion of various materials, including metals, plastics, and fiber composites.

Duffner Engineering primarily conducts failure analysis investigations and accident reconstructions. Our analysis determines product failure modes, whether related to design, manufacturing, or service. We perform environmental, structural, and/or mechanical tests in conjunction with computer-based analyses, such as finite element modeling, to determine the cause of failure.
