Reliable container line supply chains

Container line supply chains, based on a near-frictionless international transport belief, have contributed to economic prosperity and also rendered themselves uniquely vulnerable to various risks. 9/11 terrorists attacks, the lock-out of American West Ports and the global breakout of SARS disease have gradually shown that a) the safety and reliability in the chains are facing an unprecedented challenge and b) traditional engineeringbased risk assessment methods are inadequate to deal with the threats from variational environments, especially in the era of terrorism rampancy. The purpose of this paper is, therefore, to develop a conceptual risk assessment model for container line supply chains based on a modified Formal Safety Assessment (FSA) methodology that takes risks from vulnerability rather than only hazards into account. It gives particular emphasis on the analysis of the threats with a high level of uncertainty from both safety and economic viewpoints. The advantages of the vulnerability-based risk analysis approach to the hazard-based one are clarified and both engineering-based and managerial risk assessments are also discussed.

搅拌摩擦焊在铝合金船舶上的应用

使用传统铝合金焊接技术，因铝合金材料的特性，在高温下熔化，冷却后产生变形，而薄板焊接较大的变形很难校平。搅拌摩擦焊是一种新型纯机械化固相连接技术，其焊接后变形小、质量稳定、力学性能好。介绍搅拌摩擦焊的基本原理和国外的应用状况，与铝合金传统的金属焊条惰性气体焊（MTG）和钨极惰性气体焊（TIG）进行比较，分析搅拌摩擦焊应用的经济性。

A review of the Effect of α/W ratio on fracture toughness （Ⅱ） experimental investigation in LEFM

In part I of this series, experimental investigation in EPFM （elastic-plastic fracture mechanics） had been discussed. In this paper, experimental investigation in LEFM （ linear elastic fracture mechanics） is given. Fracture toughness tests had been carried out on three different strength steels, using both through-cracked specimens with different α/W ratio and semi-elliptical cracked specimens with variable crack size and shape. Results show that the fracture toughness KIC increases with decreasing α/W when α/W 〈 0.3 for three-point-bend specimens, and that for α/W 〉 0.3, it is independent of α/W. Shallow crack specimens, both through-cracked and surface-cracked, gave markedly higher values than deeply notched specimens. However, the effect of crack shape on fracture toughness is negligible. Results also show that the LEFM approach to fracture is not tenable for design stresses where αc is often very small, far less than 2.5 （ KIC/σy）^2.
