Description: This session will attempt to bring together people who are interested in applying Mechanics to nanoscale problems. In practice, differing methodologies are applied to these areas ranging from beam theory and continuum mechanics to atomic scale modeling (molecular dynamics) and hybrid methods all with some success. This tension between discrete atomic behavior and continua is both methodological and conceptual, and it effects theory, modeling, experimental practices and how we interpret data. We tend not to think of material as collection of discrete atoms, yet we can't ignore atomic discreteness at small length scales. Perhaps we measure or model individual displacements of atoms, but ultimately interpret them as stresses and strains. Talks are invited that demonstrate success and failure of traditional and innovative Mechanics methods applied to nanoscale problems. Anticipated presentation topics include but are not limited to measuring and modeling single molecule behavior, nanoscale polymer mechanics, strained semiconductor heterostructures, and small scale mechanical deformation. In addition to presentation of research, there will be a summary open forum of how our traditional notions and methods must evolve or be reworked to allow successful application to the nanoscale.
