Interaction between an elastic wave and a single pinned dislocation
(2005)
Acoustic, and more generally elastic, waves in solids are damped by several mechanisms, among which dislocation motion is believed to play an important role. This is because an elastic wave interacts with a dislocation ...
Elastic wave propagation through a distribution of dislocations
(2005)
We study the coherent propagation of an elastic wave in a two-dimensional continuous elastic medium filled with dislocation arrays randomly distributed and oriented in space. This configuration reasonably mimics grain ...
Propagation of elastic waves through polycrystals: the effects of scattering from dislocation arrays
(2006)
We address the problem of an elastic wave coherently propagating through a two-dimensional polycrystal. The main source of scattering is taken to be the interaction with grain boundaries that are in turn modelled as line ...
Elastic wave propagation through a random array of dislocations
(2004)
A number of unsolved issues in materials physics suggest there is a need for an improved quantitative understanding of the interaction between acoustic (more generally, elastic) waves and dislocations. In this paper we ...
