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.
