Expert has studied aluminum alloys from the 2xxx, 5xxx, 6xxx and 7xxx series and studied their grain size, tensile properties, heat treatments, corrosion resistance, and fatigue behavior (both room temperature stress - life (S-N) and crack growth behavior). His work is also in the area of selecting new aluminum alloy materials for applications in aircraft.

Expert has an extensive background in high temperature materials used in aircraft engines and that used in power plants. He maintains a large data base on these and other materials on the creep-fatigue behavior of materials. Other materials he studied are used in solder joints, aircraft, automobiles, and manufacturing engineering applications.

Expert has been studying metal corrosion issues on aircraft materials and components for the last 11 years. He was a principal investigator on the corrosion evaluation and mechanical properties determination of exposed C/KC 135 tanker aircraft skin materials. Materials he studied are aluminum alloys, steel alloys and titanium alloys.

Expert has been studying the creep and creep fatigue damage mechanisms in materials that were used in such applications as gas turbines, power equipment and other applications. He also studied the creep damage mechanisms under the laboratory test conditions known as low cycle fatigue and creep-fatigue interactions. Some materials studied were SS316, Ti-6Al-4V, MarM002, 1Cr-Mo-V and other superalloy blade and vane materials.

Expert has been working with the metal materials used in a range of applications such as for making valves, chemical running plant equipment, gas turbine components, and aircraft components. He has industrial experience to foresee the application requirements to suggest a material for a particular application.

Most of the work Expert has been doing over the last 15 years is to understand the mechanical behavior of materials. The mechanical behavior include such terms as tensile, fatigue, creep, corrosion, and wear behaviors in order to model the damage growth mechanisms and failure by one of these modes. The materials range from solder alloys, aluminum alloys, titanium alloys, superalloys, steel alloys and other alloys.

In order to generate a material behavi has been very active in conducting mechanical tests. He has performed tensile, hardness, wear, fatigue, creep, corrosion, wear tests and other tests on the full-scale components to determine the material behavior and predict the component life.

Expert's recent work at Cessna Aircraft Company involved conducting failure analysis of aircraft components failed in service or on the test articles while conducting tests. Since the aircraft components are made of a range of materials he has conducted failure analysis on a range of materials being non-ferrous and ferrous metal. His other failure analysis work involve failure analysis if pipes, pipe fittings used in power plants and some gas turbine engine components.

Expert has written extensively on the physics of pitting and how pitting interacts with fatigue. He has developed models to predict the pit growth rates in aluminum alloys and presented models to capture the phase in which a pit changes to a crack. The damage growth rates increase when a crack grows in a corrosion environment.

Participated in a round-robin test effort from the Air Force/Boeing Contract on the corrosion prevention and life assessment of C/KC 135 fleet. Coordinated material testing efforts for Cessna new material characterization and data reduction for the new aircraft programs.Performed failure analysis of test article components and aircraft components from service for failure mode and cause investigation.Updated the data-base and material parameters in the damage tolerance software package, CRACKS-95.Served as a consultant to various corporations such as FASIDE International, ARINC Research Corporation, Boeing Defense and Space Group, etc.
