Abstract
Nonlinear Supratransmission refers to the sudden large energy flow when a harmonic driving reaches a threshold amplitude in a system at a given frequency. In this work, supratransmission of stress wave in two-dimension ordered granular material is investigated by the Discrete Element Method (DEM). The abrupt change in spectrum distribution of stress waves can be utilized as a criterion to identify the occurrence of the supratransmission phenomenon, in which, the Lower Forbidden Band, Pass Band and Upper Forbidden Band can be clearly distinguished in the spectrum distribution diagram. The influences of friction coefficient and prestress on spectrum distribution have been expounded. The longitudinal prestress shows strong ability in adjusting the upper forbidden bandwidth. Moreover, in some frequency bands, the energy transfer efficiency increases sharply with the increase of the friction coefficient. Then, the research focus turns to the dissipation mechanism of stress waves in granular materials. According to the intensity of energy dissipation, the dissipation band is defined, in which a large part of the energy is dissipated. The coupling of the response and excitation of the boundary particles plays an important role in dissipation of stress waves. Compared with other structures, the square-packed granular material has more significant effect on the dissipation of stress wave. The results will provide new insights into the wave propagation behavior of granular materials.
期刊介绍:
The word ‘particuology’ was coined to parallel the discipline for the science and technology of particles.
Particuology is an interdisciplinary journal that publishes frontier research articles and critical reviews on the discovery, formulation and engineering of particulate materials, processes and systems. It especially welcomes contributions utilising advanced theoretical, modelling and measurement methods to enable the discovery and creation of new particulate materials, and the manufacturing of functional particulate-based products, such as sensors.
Papers are handled by Thematic Editors who oversee contributions from specific subject fields. These fields are classified into: Particle Synthesis and Modification; Particle Characterization and Measurement; Granular Systems and Bulk Solids Technology; Fluidization and Particle-Fluid Systems; Aerosols; and Applications of Particle Technology.
Key topics concerning the creation and processing of particulates include:
-Modelling and simulation of particle formation, collective behaviour of particles and systems for particle production over a broad spectrum of length scales
-Mining of experimental data for particle synthesis and surface properties to facilitate the creation of new materials and processes
-Particle design and preparation including controlled response and sensing functionalities in formation, delivery systems and biological systems, etc.
-Experimental and computational methods for visualization and analysis of particulate system.
These topics are broadly relevant to the production of materials, pharmaceuticals and food, and to the conversion of energy resources to fuels and protection of the environment.
