Abstract The static behavior of large deflection of plates is considered. The w-F governing equations for large deflection of plates are derived and Solved using Finite Element with Galerkin approach to calculate the static deflection and for parameter values which span the design space. An Incremental Iterative technique were used. The Galerkin Method was used to derive the element stiffness matrix and load victor. A three node- 18DOF Triangle Element was selected to calculate the nodal field variables. Two boundary conditions were considered, the simply supported and clamped plates. A well prepared program used for plates with small deflection,, Linear Problem,, was modified to handle the changes in the governing equations and apply the solution techniques. A good fit with previous published studies was found.

Abstract Glass fiber reinforced plastic (GRP) pipes, are widely used in many of industrial applications, such as oil industries and petrochemicals plants to transport a wide range of different liquids like fresh water, sea water, lubricant oils, acids and caustic etc. This related to their lightness, corrosion resistance, strength durability, high tensile strength, low density, and ease of installation, so that selected as better than traditional metal pipes in such applications. But the internal surfaces of these pipes can be exposed to slurry erosion due to the impact of sand particles mixed with fluids at high velocity leads to create, catastrophic failure, which limits the useful life of pipes and their efficiency. Therefore the erosion is a critical parameter for design, selection and operation of hydraulic transportation system. This thesis has studied experimentally the Slurry erosion wear behavior of GRP pips at various parameters such as impact angles, and velocity of particles. Jet type erosion tester was used as rig and sand used as solid particle mixture with water. The results clearly indicated that the factors contribute to wear of Pipes. The erosion rate or weight loss increased as time, and velocity of solid particles increased, the effect of impact angles shifts from ductile behavior to brittle behavior depending on the value of erosion efficiency. The comparison between predicted and experimental results shows agreement within ±7% for Epoxy and ±8% for Polyester.

This paper investigates the current status of the implementation level of Just-In-Time (JIT) within the Oil & Gas (OGI), Iron & Steel (ISI), Cement (CI) and Construction (C) Industries within Libya and its implication for management within the said industries. A survey methodology has been applied in this investigation using an intensive questionnaire and one-to-one interviews of the correspondent organizations. Based on the analysis of the survey questionnaire and the one-to-one interview responses, the results show that the management body does not have a clear strategy towards most of the areas that are considered as being crucial in any successful implementation of the JIT techniques. The implementation levels of the JIT techniques are found to be in the modest levels even in the organizations that have indicated themselves as JIT implementers. The research has identified management limitations within the investigated areas and has pointed to areas where the management body needs to take immediate actions in order to achieve an effective and successful JIT implementation within their organizations. This is an important finding for the future success of the Libyan industries and the similar ones. arabic 18 English 107
