Description: Multiscale modeling and simulation tools provide new insights into ways in which fine length/time-scale physics affect coarse length/time-scale constitutive responses of materials. Although the philosophical approach to multiscale mechanics has been pursued since the origins of materials modeling, its growth has accelerated with the increasing power of microprocessors. It is now commonly accepted that a robust suite of computational tools also include multiscale models.

We have therefore come to a point where simulations can frequently span the relevent scales of several different material models, and would be useful to review the new understanding that these modeling methods and techniques lend to material behavior.

This symposium focuses upon multiscale modeling that illuminates the behavior of all types of materials. Relevant length and time scales may span anywhere from electronic structures to molecular dynamics to defect field theory to macroscopic continuum modeling, thereby bringing together practioners from the fields of continuum mechanics, engineering science, computational physics & chemistry, and materials science. Abstracts pertaining but not limited to the following areas are welcome:

• crystals with defects such as
• vacancies,
• inclusions,
• dislocations,
• disclinations, and
• twins;
• piezoelectrics and magnetics;
• amorphous and semi-crystalline metals and polymers;
• polycrystalline metals and ceramics; and
• liquid crystals.

Presenters are encouraged to discuss any subtantial findings or new discoveries regarding material physics made through modeling, in addition to presentation of noteworthy theoretical or computational multiscale techniques, as applicable.
