PROFESSIONAL PRACTICE

Mechanical design engineering and analysis, fracture and fatigue, stress and load analysis, mechanical testing, and heat transfer. Testimony relating to design practice, performance and function of power transmission devices, lifting equipment, pressure vessels, off-road and agricultural vehicles, production machinery and consumer products.

Forensic practice evolved out of thirty five years design engineering experience in aerospace, nuclear, undersea and robotics industries. Assignments included design, test and project engineering in machine assemblies, welded structures, lifting and hoisting machinery, pressure equipment, hydraulic and pneumatic systems, aerospace engine research, undersea operations support equipment and nuclear fuel storage and handling projects.
