Gery Wilkowski

Gery Wilkowski is a world known expert in the area of pipelines fracture (pipelines used in the nuclear, oil and gas industry).
Qualifications:
1. Development and verification of fracture mechanics and analyses of cracks in stainless steel pipe. This work was the major contribution of Dr. Wilkowski to the ASME Boiler and Pressure Vessel Code - Section XI criteria for evaluation of cracks in austenitic and ferritic steel piping.
2. Development of experimental techniques for conducting laboratory specimen and pipe fracture experiments. The evolution of the DC electric potential method involved mapping of the surface cracks profile caused by stress-corrosion and elastic-plastic cracking, as well as fatigue.
3. Fracture mechanics analyses of cracked pipe. Analyses and experimental verification for fracture instability of axial, circumferential and helical cracks in pipes for nuclear, oil and gas transmission lines, downhole tubular products and offshore platforms has been performed in numerous programs.
4. Pipe flaws instability analysis. A crack energy balance stability analysis to assess start of instability and crack arrest for circumferentially cracked pipe, including transition of surface cracks through wall.
5. Stability of cracked pipe under dynamic loading. A cracked pipe segment modeling to simulate circumferentially cracked pipe under seismic loading by dynamic finite element beam analysis developed and verified in several large programs.
G. Wilkowski has also been involved in numerous other projects, some of which are: crack initiation and arrest in liquid natural gas storage tanks, material design of low temperature hazardous containers, optimization of wear and fracture characteristics of snow plow blades, design of large arctic high pressure vessels, designing secondary hydrostatic tests for oil and gas pipelines, fracture behavior of pipelines buried in permafrost, fracture analysis of railroad tank cars, fracture of arctic grade valves, flanges, and fittings, steam generator tubing rupture analyses, fracture toughness requirements for nuclear shipping casks, experimental evaluations of girth welds in large diameter pipe, crack arrest considerations for liquid CO₂ pipelines, design and optimization of mechanical crack arrestors for pipelines, fracture behavior of valves and elbows, developing failure criteria for helical flaws in spiral weld pipe under combined pressure and bending loads, developing the drop weight tear test used for measuring dynamic ductile fracture toughness of natural gas transmission piping, elastic-plastic low-cycle fatigue crack growth analysis of pipe girth welds, transition of unstable axial cracks to circumferential crack in CANDU reactor pressure tubes, and numerous field failure investigations for oil and gas companies.
Management experience
G. Wilkowski was the principal investigator and developer of the U.S. Nuclear Regulatory Commission's Second International Piping Integrity Group (IPIRG-2) program. He was the program manager of NRC's Short Cracks in Piping and Pipe Welds program, managed a program on crack arrest in offshore platforms as well as a program for the American Gas Association's Welding Supervisory Committee on girth weld defects in pipelines. He managed numerous programs involving fracture control prevention for the Alaskan natural gas pipelines and several programs on the dynamic analyses of cracked nuclear piping systems.
