Tracking and Perspectives on WTO Negotiations: from Geneva to Hong Kong , July-December 2005

This month's issue of the FAL Bulletin takes a panoramic view of the present World Trade Organization (WTO) trade negotiations, soon to embark on the Sixth Ministerial Conference in Hong Kong (Special Administrative Region of the People's Republic of China ). Reduced expectations on the outcomes of this meeting due to the scant progress on critical issues - such as the liberalization of the agricultural sector - increase the challenge to conclude the Doha Round by the end of 2006. The governments of the region have a role to play in the direction this process may take. Additional details on the progress of these objectives can be obtained in chapter II of Latin America and the Caribbean in the World Economy, 2004 Trends 2005.

A local-global scheme for tracking crack path in three-dimensional solids

This paper aims to contribute to the three-dimensional generalization of numerical prediction of crack propagation through the formulation of finite elements with embedded discontinuities. The analysis of crack propagation in two-dimensional problems yields lines of discontinuity that can be tracked in a relatively simple way through the sequential construction of straight line segments oriented according to the direction of failure within each finite element in the solid. In three-dimensional analysis, the construction of the discontinuity path is more complex because it requires the creation of plane surfaces within each element, which must be continuous between the elements. In the method proposed by Chaves (2003) the crack is determined by solving a problem analogous to the heat conduction problem, established from local failure orientations, based on the stress state of the mechanical problem. To minimize the computational effort, in this paper a new strategy is proposed whereby the analysis for tracking the discontinuity path is restricted to the domain formed by some elements near the crack surface that develops along the loading process. The proposed methodology is validated by performing three-dimensional analyses of basic problems of experimental fractures and comparing their results with those reported in the literature.
