Announcement:
On Monday, August 19, 2002 prior to the technical sessions
for AEWG-45 a one-day short course
(The Primer) will be presented in the second floor conference
room of the ITEC building, 1801 Maple Avenue, Evanston, IL.
The course will cover fundamentals of acoustic emission,
instrumentation, materials and applications. The Primer is
designed to bring newcomers to Acoustic Emission up to speed
to participate in the Working Group technical sessions. The
content and selection of speakers make the Primer a valuable
refresher for those wishing to update their expertise in
the field. Four outstanding leaders in the field of acoustic
emission will present this year's primer.
The topics and presenters are:
Introduction to Acoustic Emission
and Instrumentation…….Dr. Richard Nordstrom
Rick Nordstrom has been an AE application scientist for
two AE instrument manufacturers, Physical Acoustics Corporation,
Princeton, NJ (1986-1989) and Vallen- Systeme, Munich Germany
(1996-1999). He has earned degrees in Electrical Engineering
and Material Science at the Massachusetts Institute of Technology,
Cambridge, MA and a Doctor in Mechanical Engineering (wave
mechanics) at the Swiss Federal Institute of Technology,
Zurich, Switzerland. He has also worked at the Swiss Federal
Testing Laboratory for Materials Testing. He is now a research
faculty at Portland State University.
Acoustic Emission in Metals………...……………………………….Harold
L. Dunegan
Hal Dunegan conducted his first AE experiment at Lawrence
Livermore Laboratories in 1963. At the formative meeting
of the AEWG in 1967 Mr. Dunegan was elected as the first
chairman of the AEWG. Mr. Dunegan formed Dunegan Corporation
in 1968 the first company exclusively devoted to the manufacture
of Acoustic Emission sensors and instrumentation for world
markets. Dunegan Corporation was sold to Physical Acoustics
Corp. in 1985. Mr. Dunegan then formed Dunegan Engineering
Company Inc. in 1987 and he is presently President of this
company. He is a recipient of both the Gold Medal, and Achievement
Award from AEWG.
Acoustic Emission in Composite
Materials………………………..Dr.
Marvin Hamstad
Marv Hamstad has been continuously involved in acoustic
emission research and applications since 1971, and he has
carried out AE projects in the USA, Germany, and Sweden.
Dr. Hamstad completed his Ph.D. in Mechanical Engineering/Solid
Mechanics at the University of California, Berkeley, CA,
USA in 1971. From 1971 to 1984 his AE research and development
efforts were carried out at Lawrence Livermore National Laboratory
(LLNL; Livermore, CA, USA). Lawrence Livermore was one of
the "birthplaces" of acoustic emission technology
in the United States. From 1984 to the present, Dr. Hamstad
has continued his acoustic emission work at the University
of Denver (Denver, CO, USA). Dr. Hamstad has also provided
key leadership as chairman of the CARP (Committee on Acoustic
Emission from Reinforced Plastics) Division of the American
Society for Nondestructive Testing. He completed sixteen
years as CARP chairman in 1999. Dr. Hamstad's research has
covered many areas of acoustic emission technology ranging
from nondestructive testing (NDT) applications to materials
characterization.
Acoustic Emission in Large Structures
and Pressure Vessels……….Dr. John Carlyle
John Carlyle is the Chief Scientist for Carlyle Consulting,
a small business firm which conducts research and engineering
for NDT related problems. He has over thirty years of extensive,
direct experience in applying acoustic and electromagnetic
NDT techniques to locate and identify defects in complex,
engineered structures (such as aircraft, bridges, cranes,
high pressure steam lines, and buried pipelines) with the
objective of determining if they are fit for their intended
purpose. During his career he has designed, engineered and
built several turnkey systems for the routine, periodic acoustic
inspection of entire aircraft structures (F-111 and VC-10),
and he has directed over fifty government and commercial
contracts. He holds a B.S. in Physics from Carnegie Institute
of Technology, Pittsburgh, PA, as well as a M.Sc. in Nondestructive
Testing and a Ph.D. in Physics from Brunel University, London,
England. Dr. Carlyle has received U.S. and European patents
on two acoustic instruments, is a Fellow in both the American
Society for Nondestructive Testing and the Acoustic Emission
Working Group, and has authored over ninety NDT related publications.
