WAVE PROPAGATION IN ELASTIC MEDIA WITH NANOSTRUCTURES

摘要：

Accurately understanding and describing the high-frequency dynamic properties of elastic media with nanostructures are fundamental concerns and challenging problems in designing and predicting performance of nano-devices.The use of molecular dynamics (MD) to model and analyze the properties of nanostructured materials is very heavy on computing time.The goal of this paper is to develop a multiscale continuum theory for the analysis of wave propagation in the elastic media with nanostructures.The key step in this approach is the establishment of a relationship between the local kinematics and the global continuum variables.The model is capable of accounting for local deformation of nanostructures.
