LEE A. JAMES

Over thirty years of experience devoted exclusively to the application

of fracture mechanics technology to structural components, particularly

in the interface between engineering mechanics and materials science.

Expertise includes experimental characterization of subcritical crack growth

and fracture toughness, analytical prediction of in-service cracking behavior,

plus some involvement in failure analysis of components.

PROFESSIONAL WORK EXPERIENCE

June 1998

- Present

Independent consultant in the area of fracture mechanics applications,

particularly in the field of environmentally assisted cracking and stress

corrosion cracking. Substantial references and resources are available

in K-solutions for complex structural components, crack growth behavior,

and fracture toughness prperties. Providing support to Pressure Sciences

Incorporated on an as-requested basis.

1987

to May, 1998 - Advisory Engineer

Westinghouse, Bettis Atomic Power Lab.

Consultation on fracture mechanics testing and structural applications,

development of programs to address specific fracture mechanics concerns,

and development of fracture mechanics analysis methods. Responsibility

included all pressure vessel, piping, and structural materials in naval

nuclear power plants, exclusive of core materials. Specific areas

of emphasis included formulating, conducting, and managing programs to

demonstrate mitigation of stress corrosion cracking and environmentally-assisted

cracking concerns in naval nuclear structural components in agueous environments,

and developing analytical / experimental programs to characterize the effects

of constraint upon fracture toughness of structural alloys. Played

a lead role in the formulation and implementation of fracture mechanics

analysis methods, particularly as they related to environmentally-assisted

cracking (EAC). Electrochemical characterization of EAC processes.

Participated in failure analy-ses of service-exposed components.

1970

to 1987 - Fellow EngineerWestinghouse Hanford Company

Research into the fatigue and fracture characteristics of metals at

elevated temperatures and under aggressive environments, with emphasis

on nuclear environments. Determined the effects of temperature, frequency,

environment, stress ratio, waveform, neutron irradiation and metallurgical

variables on crack propagation behavior of ferritic and austenitic steels

and nickel-base alloys. Investigated the fracture toughness (KIc

and JIc) of structural alloys. Developed experimental and analytical

procedures to apply fracture mechanics to structural analyses. Performed

analyses to predict cracking behavior of reactor components operating under

complex service conditions, prepared PSAR and FSAR sections covering these

analyses, and testified on the findings before hearings of the NRC and

ACRS. Directed stress-corrosion cracking research in support of the

Basalt Waste Isolation Project (long-term storage of high-level nuclear

waste).

1967

to 1970 - Senior Research EngineerBattelle Memorial Institute, Pacific Northwest Lab.

General fatigue and fracture mechanics research. Investigation

of the effects of various service environments on the subcritical cracking

behavior of structural alloys, including steels, aluminum alloys and zirconium

alloys. Developed an experimental technique for obtaining the stress

intensity factor relationship for complex structural shapes.

1965

to 1967 - Research EngineerThe Boeing Company, Commercial Airplane Division

Structural development research on the supersonic transport. Formulation

of analysis techniques and design criteria to use in the analyses of thermal

stresses in complex aircraft structures. Theoretical analyses verified

by extensive high-temperature testing. Structural analyses on 747

jet transport. Determination of structural loads and detailed stress

analysis of mechanisms and associated structures.

1964

to 1965 - Graduate Research Assistant

University of Washington, Mechanical Engineering Dept.

Conducted research into the plastic strain distribution at the root

of a sharp notch. Work was conducted under a research grant from

the Office of Naval Research,

Washington, D.C.

1960

to 1964 - Design EngineerThe Boeing Company, Aero-Space Division

Mechanical design of mechanisms for the X-20 Dyna-Soar space glider.

Responsible for the development, design and installation of highly reliable

high-temperature mechanisms. Duties included feasibility studies, stress

analysis, weight studies, heat transfer analysis, and experimental testing.

PROFESSIONAL AFFILIATIONS

Fellow, American Society of Mechanical Engineers

American Society for Metals

American Society for Testing and Materials

National Association of Corrosion Engineers

Society of the Sigma Xi (professional scientific research honorary)

NATIONAL COMMITTEE ASSIGNMENTS

Member, Subgroup on Fatigue Strength, ASME Boiler and Pressure Vessel Code

Committee. Lead role in the formulation and drafting of a crack propagation

relationship for austenitic steels for Section XI of the ASME B&PV

Code. Although under the auspices of the ASME Code Subgroup, most

of the work was actually carried out working in the PVRC/MPC Task Group

on Crack Propagation Technology. Presently drafting a Code Case for

environmentally-assisted cracking of pressure vessel steels.

Member, Committee E-08 (Fatigue and Fracture) of ASTM. Active in

the preparation of the Standard Method of Testing for Fatigue Crack Propagation

(Standard E647), and the ASTM Standard on Stress Corrosion Cracking testing

(E1681).

Awards"

Lee won the ASME Robert J. McGrattan Literature Award for the best paper

in the Journey of Pressure Vessel Technology for 1997. The

paper was entitled "The Effect of Water Flow Rate Upon the Environmentally

Assisted Cracking Response of a Low Alloy Steel: Experimental

Results Plus Modeling."
