133 Committee “Microstructures and Functions of Materials” of University-Industry Research Cooperation Program
of Japan Society of Promotion of Science organizes the above compact international symposium, in which interactions between theorists
and experimentalists are emphasized. We would like to welcome researchers in this field in the world to participate in the Symposium
and to contribute to it.
Incidentally, the Symposium is held just before a related international conference
“The 9th International Conference on Multiscale Materials Modeling” in Osaka, Japan.
Background and scope:
Crystal plasticity has been investigated mostly in terms of the theory of crystal dislocation, which developed rapidly after the Second
World War. Various aspects of crystal plasticity had been formulated until 1980’s by the dislocation theory which was based mainly on
the elasticity theory without reliable atomistic information. Hence, the present understanding of the crystal plasticity is more or less
qualitative. From the end of 20th century, however, atomistic analyses have become possible due to the development of atomic resolution
microscopy in the experimental side and to the development of first principle calculations in the theoretical side.
It becomes now possible to analyze the crystal plasticity taking full account of atomistic analyses, and thus to bring about a better,
hopefully quantitative, understanding of crystal strength. The Symposium lays particular emphasis on the interaction between theorists
and experimentalists, which seems so far quite lacking.
