Computer Simulation Study of Mechanical Properties of Nanoscale Materials by Molecular Dynamics and Lattice Green’s Function Methods

Masuda-Jindo K., Menon M., Hung V-V, Tokyo Institute of Technology, JP

The mechanical properties of nanoscale materials are studied using the molecular dynamics and lattice Green’s function methods. The initial atomic structures of the dislocations and cracks are determined both from the elastic solutions as well [...]

Size Effects and Scaling in Misfit Dislocation Formation in Self Assembled Quantum Dots

Friedman L.H., Weygand D.M., van der Giessen E., University of Groningen, NL

Growth islands due to large mismatch strain arising in Stranski-Krastanow (SK) and Volmer-Weber (VW) ﬁlm growth can be used to produce large arrays of quantum dots. This same mismatch strain may also cause misﬁt dislocations [...]

Nanomanipulation and Characterization of Individual Carbon Nanotubes

Ruoff R., Northwestern University, US

A new tool that operates in a scanning electron microscope for measuring the mechanics of nanostructures is briefly presented, and its use to measure the response to tensile loading of carbon nanotubes is outlined.

Phase Field Modeling of Dislocation Network Coarsening, Dislocation – Impurity, and Dislocation – Precipitate Interactions

Shen C., Kazaryan A., Anderson P.M., Wang Y., Ohio State University, US

Interactions of dislocations with one another and their interactions with impurities and precipitates determine the behavior of plastic deformation of crystalline materials. In this presentation, we will discuss recent advances in phase field modeling of [...]
