Abstract

Purpose

Continuum-based discrete element method is an explicit numerical method, which is a combination of block discrete element method (DEM) and FEM. When simulating large deformation problems, such as cutting, blasting, water-like material flowing, the distortion of elements will lead to no convergence of the numerical system. To solve the convergence problem, a particle contact-based meshfree method (PCMM) is introduced in. The paper aims to discuss this issue.

Design/methodology/approach

PCMM is based on traditional particle DEM, and use particle contacts to generate triangular elements. If three particles are contact with each other, the element will be created. Once elements are created, the macroscopic constitutive law could be introduced in. When large deformation of element occurs, the contact relationship between particles will be changed. Those elements that do not meet the contact condition will be deleted, and new elements that coincide with the relationship will be generated. By the deletion and creation of elements, the convergence problem induced by element distortion will be eliminated. To solve FEM and PCMM coupled problems, a point-edge contact model is introduced in, and normal and tangential springs are adopted to transfer the contact force between particles and blocks.

Findings

According to the deletion and recreation of elements based on particle contacts, PCMM could simulate large deformation problems. Some numerical cases (i.e. elastic field testing, uniaxial compression analysis and wave propagation simulation) show the accuracy of PCMM, and others (i.e. soil cutting, contact burst and water-like material flowing) show the rationality of PCMM.

Originality/value

In traditional particle DEM, contact relationships are used to calculate contact forces. But in PCMM, contact relationships are adopted to generate elements. Compared to other meshfree methods, in PCMM, the element automatic deletion and recreation technique is used to solve large deformation problems.

Abstract

Purpose

The purpose of this paper is to examine the different strategies implemented by a number of successful Chinese firms currently striving to build global brands in order to improve their export capabilities. A particular emphasis is put on the transfer of marketing technology for brand engineering in order to achieve this goal.

Design/methodology/approach

The analysis uses case study methodology to understand what many prominent Chinese exporting firms have achieved, and develops a theory about their general strategy. Five firms have been chosen: Lenovo, Haier, Cosco, Tsingtao, Geely. Aside from these five, information is also given on the branding strategy of Li Ning and Suntech Power. A great part of the information collected is coming from “desk research”, except for Haier, Lenovo and Tsingtao for which personal contacts and visits took place in 2005 and 2006.

Findings

The findings suggest that some of the most successful Chinese firms in the field of development of brand image either use some marketing tools, such as increasing their communication spending, improving quality control, emphasizing their corporate social responsibility visibility, or by seeking a partnership through mergers/acquisition with successful foreign brands. A basic global branding model has been defined as consistent with Chinese firms’ experience.

Research limitations/implications

The study was limited to seven firms to be considered among the most successful Chinese businesses. It does not intend to be perceived as statistically representative. The period of observation of the effect of the strategy which was implemented was short and during a time of booming Chinese economy. It was impossible to isolate the extraneous variables linked to the economic or competitive situation, knowing that they could affect the observations on the firms that were studied.

Originality/value

Though the entry strategies on the Chinese market as well as inbound foreign direct investments have been the object of a great number of publications, the outbound strategies of Chinese exporting firms, as well as the impact of technology transfer, has been covered less frequently. Therefore, this paper can have value for candidates for the improvement of global branding.
