Abstract

Green Supply chain, Green Packaging, Eco-labels, and Eco-design strategies are concepts that are discussed frequently within scientific and political debates. Eco-design strategies for Lifecycle Design include the Eco-design Strategy wheel which presents eight Eco-design strategies: New concept development, Selection of low-impact materials, Reduction of materials usage, Optimization of production techniques, Optimization of distribution system, Reduction of impact during use, Optimization of initial lifetime, and Optimization of end-of-life system. This research investigates specifically the selection of low impact raw materials phase using the European Union as a benchmark to improve the Egyptian situation and aims to apply the closed loop cycle to the Egyptian Plastics Industry. Its goal is to enlight the way towards Sustainable and Circular economy system in Plastics manufacturing sector in Egypt while emphasizing the financial benefits from the Business and Marketing perspectives rather than the Environmental perspective only.

Abstract

Designers have a major interest about fatigue properties of materials used in transport industry. Each component in transport works under alternating stress. From this point of view the fatigue properties are important for single parts lifetime resulting into safety of whole components as cars and airplanes what leads to safety on the roads or air and have influence on human life as well. Therefore this paper deals with fatigue properties of wrought Inconel alloy IN 718 and aluminum cast alloy AlSi9Cu3. Both materials were put on fatigue push – pull test, but Ni – based IN 718 alloy at frequency of loading around 20 000 kHz (High Frequency High Cycles Fatigue) and aluminum alloy AlSi9Cu3 at frequency of loading around 80 Hz (Low Frequency High Cycles Fatigue). These parameters were chosen with respect of usage such materials for production of components used in transport industry applications. Results after fatigue tests are presented as Wohler curve. For prediction of source of fracture the SEM fractography analysis of fatigue fracture surfaces was made.
