Dr. Lemberg is a licensed Metallurgical Engineer specializing in failure analysis, fracture mechanics, metallurgy, and materials science engineering with a particular emphasis on understanding the fracture behavior of materials. He has consulted on pipeline failures, storage tank failures, heavy equipment failures, brass systems for potable water, glass cookware and drinkware, medical devices, corrosion issues in the transportation industry, as well as various other materials issues.
Dr. Lemberg has experience diagnosing failures in both ferrous and non-ferrous metal systems, ceramics, glasses and polymeric materials. He has expertise in mechanical testing, especially in the area of crack-growth resistance testing, as well as optical and electron microscopy, metallography, and fractography.
Prior to joining Exponent, Dr. Lemberg was a graduate research assistant at the University of California, Berkeley, where he studied the fracture behavior of Mo-Si-B alloys at ambient and ultra-high (1300 °C) temperatures, the fracture behavior of carbon-nanotube-impregnated, Nb-toughened nanocrystalline alumina, and the fracture behavior of alumina/silicon nitride functionally-graded joints at elevated temperatures. Dr. Lemberg also has experience studying the fatigue properties of tree-resistant cross-linked polyethylene insulation of underground power distribution cables.
