An Investigation of Behavior of Metal Flow between Flat and Overlapping Dies When Forging Commercial Copper

Abstract Forging in a flat and overlapping dies have many industrial applications, and many parts can be produced, parts with ends of different shapes, and study of such process is important to understand the mechanic, and effect of different variables, Specimen shape, die geometry. In this work, a study forging of copper specimens between flat dies and overlapping dies having cylindrical, rectangular and square cavities, were fixing cross-section area in all specimens and changing the shape of cross-section area. Load displacement relationships were presented and study the effect of friction and constrained volume shapes on flow behavior and effect of (D0/H0) ratio are also investigated. Double extruded part with a hub are produced by the combined forward and backward extrusion forging process, and comparison between the results of constrained volume with double extrusion part was made.

Voltage stability of the Libyan network after its enhancement by new stationary and mobile units and new 220-400KV transmission Lin

Abstract The conflict that took place in Libya in 2011, up to the present moment, has greatly affected the electrical power network and resulted in the rise of the voltage instability problem. This was due to loss of the some major transmission lines and certain generation units. Owing to the fact that the southern region of the Libyan network has no generation units, voltage drop phenomena has become a common problem as a result of the long transmission distance, which is approximately 750km. A proposed solution in order to solve this problem is via the utilization of small mobile generation units at the network weak points. This thesis revolves around discussing the voltage instability problem within the Libyan Network and how it can be enhanced when small and mobile generation units are connected to the network weak points. It will also establish and identify where the most weakened buses and regions are so that the mobile units should be connected for the attainment of optimized solution. Moreover, this solution was proposed as it can solve not only the voltage instability problem, but it will also solve the inadequacy in generation issue by circulating additional power within the network. Hence, reduce the load shedding phenomena. Furthermore, the thesis also includes future recommendations to improve and enhance the Libyan network by the addition of new 220kV and 400kV transmission lines that will enable the network to cope with the load growth in the future

CONCRETE MIX DESIGN USING SIMPLE EQUATIONS

The behaviour of concrete, whether fresh or hardened, depends basically on the behaviour of its components and the relationship between them, therefore, obtaining a concrete with certain properties depends fundamentally on the concrete mix design. Concrete mix design generally includes two main steps: 1-Selection of the main components suitable for the concrete (cement, aggregate, water, and additives); 2-Determination of more economical mix ratios to fulfil the workability, strength and efficiency requirements. Currently, there are many international methods locally approved for mix designs. They are all related to each other, they give relatively the same quantities of the mix components and they are all capable of providing a good concrete mix. It is important to consider that these methods give approximate quantities which should be checked by experimental mixes in order to obtain results suitable for the requirements of the local environment and local materials. The ACI and BS methods are the most commonly used. Both of these methods depend on graphs and standard tables derived from previous research experience and actual concrete production as well as studies of the properties of the materials used. This paper illustrates a new approach for concrete mix design named as: “Double Coating Method”, which is currently used in some research centers in the republic of Poland and was recently applied in the laboratories of the Civil Engineering Departments in the Universities of Tripoli and Benghazi in Libya. This paper describes experiment in which 24 mixtures were used to assess the usefulness of this technique for problem of proportioning concrete mixtures in general. arabic 5 English 37
