Dr. James applies the fundamental principles of metallurgy, materials science, engineering mechanics, electrochemistry, and quantitative risk analysis to the investigation and prevention of failures in engineering systems, devices, structures, and products. Dr. James' specific expertise includes metallurgical and materials engineering, fracture mechanics, fractographic examination, corrosion, material embrittlement and degradation, welding and joining, risk analysis, life prediction, material selection, and design.

In his more than 30 years' experience, Dr. James' broad understanding of materials, mechanics, electrochemistry, and risk concepts allows him to consult within several diverse industries. He has led multidisciplinary investigations in power generation and transmission, oil and gas, medical device, transportation, aviation, mining, fire protection, and consumer products industries.

Dr. James has served as an Adjunct Professor at Stanford and Santa Clara Universities, teaching several graduate-level courses that include metallurgical/materials failure analysis, fractography, fracture mechanics, mechanics of materials, and electrochemistry concepts. Dr. James has also taught dozens of day-long failure analysis, fracture, corrosion, and materials design courses to medical device engineers for ASM International. He is a Fellow of ASM International (the world's largest materials engineering technical society) and has served on the editorial review board of the Journal of Failure Analysis and Prevention.

Prior to joining Exponent, Dr. James was employed as a Research Engineer, Materials Performance Division, at the Babcock and Wilcox Research and Development Center in Alliance, OH. In this role he conducted fatigue, fracture, and corrosion testing and analyses of materials with power generation and aerospace applications.

Oil and Gas

Dr. James has conducted dozens of failure analysis investigations of oil and gas facilities, pipelines, and components. Dr. James has also helped assess the fitness for service and flaw tolerance of pipelines and associated components. The following list a few examples of his oil and gas work.
- Separator failure: Dr. James led a failure analysis investigation into how and why a natural gas separator experienced a catastrophic breach.
- Sulfidation analyses: Examined sulfidation-induced breach in refinery steel piping.
- Hydrotest failure analyses: Dr. James has conducted failure analysis investigations to determine the cause of gas pipelines that ruptured during hydrotesting.
- Sierra-Nevada Pipeline Leak: Analyzed a pipeline leak in the Sierra-Nevada mountains that occurred due to damage from improper installation that occurred some 50-years prior to the leak. The local damage resulted in increased stresses that initiated slow-growing "near-neutral" stress-corrosion cracking.
- LEFM-fatigue analysis: Assessed the risk of fatigue-crack growth, leakage, and rupture in pipelines with seam-weld defects of varying depths and lengths using linear-elastic fracture mechanics. This work provided the basis for the client to establish a methodology for seam-weld defect assessment.
- Estuary pipeline rupture: Investigated the cause of a pipeline rupture that occurred within an estuary. Evaluated the cause and extent of corrosion that led to the rupture.
- High pH SCC rupture: Evaluated the cause of a gasoline pipeline rupture that occurred in a high-population area in Arizona. The cause of the rupture was high-pH stress-corrosion cracking (SCC). Dr. James recommended hydrotesting of adjacent pipeline areas, which revealed other SCC locations that were close to rupture.
- Nevada 3rd party damage: Conducted a failure analysis investigation of a gasoline pipeline that leaked in the desert outside of Las Vegas. This pipeline had suffered a gouge from third-party digging. A fatigue crack initiated from the gouge and eventually grew through wall to cause a leak.
- Bellingham Washington pipeline: Helped investigate the cause of a ruptured gasoline pipeline rupture that tragically killed three youths. Dr. James participated in investigations at the NTSB and Exponent laboratories. The pipeline failed several years after it had been severely damaged by an excavator.
- Seam weld defect- Sacramento: Investigated the cause of a gasoline pipeline leak that occurred along an electric-resistance weld (ERW) seam near Sacramento, CA. The leak was caused by fatigue crack growth that initiated and grew from the seam weld defect.
- Seam weld defect - Texas: Investigated the cause of a gasoline pipeline rupture that occurred in Texas. Metallurgical examination indicated the rupture occurred at an improperly welded ERW seam. A fatigue crack initiated and grew in the weld seam until it reached sufficient length to cause the rupture.
- Australian Gas Pipeline SCC risk assessment: Participated in a study to assess the risk of rupture in an Australian natural gas pipeline that exhibited significant stress corrosion cracking (SCC). This analysis included using the results of in-line inspection coupled with fracture mechanics to help determine the risk of rupture.
- Tee failure: A tee at an oil refinery ruptured resulting in release of product and environmental damage. Metallurgical analysis indicated that the tee failed due to a creep-rupture mechanism, caused by excessive temperature.
- Ethanol storage tank weld: An ethanol storage tank fractured at a weld, resulting in significant loss of product and damages. Analysis indicated that the tank fractured from stress-corrosion cracking at the weld heat-affected zone.
- Gasoline storage tank failure analysis and integrity assessment: Analyzed the cause of a gasoline tank failure, and conducted a fracture mechanics-based fitness for service analysis for floor-to-shell repair welds.

- Chemical processing valve: Determined the cause of failure of a large gate valve at a chemical processing plant. A combination of insufficient bolt torque and vibration resulted in insufficient bolt clamping force, which resulted in fatigue failure.
- Piping creep: Inspection of piping at a chemical processing plant revealed local bulging of adjacent piping. The cause of the failure was creep-rupture from excessive temperatures, and that the higher than desired temperatures occurred because of deposits that restricted cooling.
- Valve bolt failures: Bolts at a chemical processing facility fractured causing a large loss. Analysis indicated that the bolts fractured due to stress-corrosion cracking. Material and environmental changes were recommended to eliminate the problem.
