Dislocations in amorphous materials
2014 The general aim of this paper is to provide a better understanding of amorphous materials, with special reference to glassy and granular systems, indicating areas where the behaviour of these two may be similar. We lay special emphasis on granular systems, as befits their importance as a newly emerging field of study in physics, and present a review of recent progress in understanding thei...

متن کاملReversible plastic events in amorphous materials.
For crystalline materials, the microscopic origin of plasticity is well understood in terms of the dynamics of topological defects. For amorphous materials, the underlying structural disorder prevents such a description. Therefore identifying and characterizing the microscopic plastic events in amorphous materials remains an important challenge. We show direct evidence for the coexistence of re...
متن کاملInversion of diffraction data for amorphous materials
The general and practical inversion of diffraction data-producing a computer model correctly representing the material explored-is an important unsolved problem for disordered materials. Such modeling should proceed by using our full knowledge base, both from experiment and theory. In this paper, we describe a robust method to jointly exploit the power of ab initio atomistic simulation along wi...
متن کاملStudy of Shear Viscosity of Amorphous Materials
Viscoelastic properties of amorphous solids deformed under uniform shear stress were studied using a kind of sandwich method with utilizing a sensitive optical technique. Time-dependent deformation data were analyzed on the basis of a mechanical model of anelasticity plus viscosity. Experiments were performed to determine the temperature dependence of viscosity for several kinds of inorganic gl...
