Mesoscopic properties of dense granular materials: An overview

Qicheng SUN, Feng JIN, Guohua ZHANG

Frontiers of Structural and Civil Engineering 2013, Volume 7, Issue 1, Pages 1-12 doi: 10.1007/s11709-013-0184-z

Abstract: A granular material is a conglomeration of discrete solid particles. It is intrinsically athermal because its dynamics always occur far from equilibrium. In highly excited gaseous states, it can safely be assumed that only binary interactions occur and a number of kinetic theories have been successfully applied. However, for granular flows and solid-like states, the theory is still poorly understood because of the internally correlated structures, such as particle clusters and force networks. The current theory is that the mesoscale characteristics define the key differences between granular materials and homogeneous solid materials. Widespread interest in granular materials has arisen among physicists, and significant progress has been made, especially in understanding the jamming phase diagram and the characteristics of the jammed phase. In this paper, the underlying physics of the mesoscale structure is discussed in detail. A multiscale framework is then proposed for dense granular materials.

Phase I Construction of the TPG——Macro Decision-Making

Peng Qiyou

Strategic Study of CAE 2004, Volume 6, Issue 5, Pages 83-86

Abstract:

In this paper, the dominance of the state-owned enterprise and current situation in ferms of project management are analysed on the basis of the sum up of phase I construction management of the TGP. From the view point of the change of the way of thinking and the deepening of internal reform of enterprise, some of concrete suggestions for enhancing the project management are given in the paper.

Assembly design system based on engineering connection

Wensheng YIN

Frontiers of Mechanical Engineering 2016, Volume 11, Issue 4, Pages 423-432 doi: 10.1007/s11465-016-0382-1

Abstract:

An assembly design system is an important part of computer-aided design systems, which are importanttools for realizing product concept design.The traditional assembly design system does not record the connection information of production on theengineering layer; consequently, the upstream design idea cannot be fully used in the downstream designAn assembly design model based on the relationship of engineering connection is presented.
