Investigation of Ductile Fracture Arrest of High Strength Steels for Gas Pipeline Application
The ductile fracture arrest may present supplementary requirement for selection of base material for most demanding steel welded structures. The most representative one with such requirement are gas pipelines. Therefore to ensure that the pipeline materials has adequate toughness to arrest a ductile fracture, the pipe material must be designed and tested in accordance with the specific procedur...
متن کاملThe Impact of EU’s Competition Laws on the Long-Term Gas Contracts
Competion laws follow varions goals including economic targets such as increase of economic efficiency and consumers' welfare. This branch of law has resisted against agreements and contracts which endanger the consumers' or public welfare and has tried to prevent such contracts and processes. European Union is among the greatest consumers and importer of energy in the world. The most part of t...
متن کاملImpact of Long-term Debt on Overinvestment Problem of Agency
Business units are always faced with investment opportunities and need to make logical decisions on an optimal investment. Indeed, the investment of each business unit should be done with regard to the resource constraints and its effectiveness through the criteria for evaluating the projects including the net present value (NPV). The paper aims to investigate the effect of long-term debt on th...
متن کاملthe impact of skopos on syntactic features of the target text
the present study is an experimental case study which investigates the impacts, if any, of skopos on syntactic features of the target text. two test groups each consisting of 10 ma students translated a set of sentences selected from advertising texts in the operative and informative mode. the resulting target texts were then statistically analyzed in terms of the number of words, phrases, si...
15 صفحه اولIndustrial application of Instrumented DWTT in evaluating material resistance to ductile fracture for modern pipeline steels
CTOAC of typical X70, X80 and X90 pipeline steels plates were evaluated by using energy based regression method upon their single specimen. Clear difference in the material resistance to ductile cracking could be distinguished by the values of CTOAC and their characteristic fracture surface. The region of stable cracking on the fracture surface could be identified from the dynamic crack extensi...
