Critical Technology Sector, Jt. Mechanical Behavior of Materials
This symposium is organized to honor the work of Professor Ron Armstrong.
The focus is on the dynamic behavior of materials, with emphasis in areas
in which Prof. Armstrong has made seminal contributions: constitutive
equations and grain-size effects. Dynamic deformation encompasses a broad
range of phenomena with technological applications in military and civilian
sectors. This will be the third in the series of symposia held on this
subject, with the first symposium held in October 1994 and the second
in October 1998, both in Rosemont, Illinois. Grain size effects on plastic
deformation of materials have been a subject of consistent interest since
the days of Hall and Petch, and the recent thrust in nanocrystalline materials
has raised the interest to even higher levels. The macromechanical and
physical processes that govern deformation at high-strain-rates and in
materials with nanocrystalline grain sizes manifest themselves by a dazzling
complexity of effects and morphologies. Professor Armstrong’s noteworthy
contributions in these areas have enhanced our predictive capability by
enabling an improved understanding of the deformation mechanisms. The
purpose of this symposium is to bring together researchers working in
dynamic high-strain-rate deformation of solids, and on effects of grain
size on plastic deformation, in particular, of nanocrystalline materials.
The objective will be to review the state of the understanding of deformation
mechanisms and mechanical properties as they are influenced by high-strain-rate
and grain size effects. Unique consequences of dynamic deformation, including
stress-induced chemical and physical changes, will also be discussed.
The symposium will include invited and contributed papers in the following
areas: high-strain-rate mechanical properties; mechanisms of dynamic deformation;
constitutive equations; grain size effects on mechanical properties; strengthening
mechanisms in nanocrystalline solids; stress-induced physical and chemical
changes in inert and energetic materials. The organizers are planning
to publish the proceedings from this symposium in Metallurgical
and Materials Transactions.
