Need an research paper on materials: a stainless steel 316l (ss-316l). Needs to be 5 pages. Please no plagiarism. 1. The best performance in terms of Young’s modulus to density ratio
2. The best performance in terms of Young’s modulus to the cost-density ratio
3. The best performance in terms of Stiffness to recycle ratio of a maximum of 100 GBP/Kg.
The basic criterion to a satisfactory design is to create products that can perform their function effectively, safely, and at an acceptable cost. For designing an object the selection of material plays a critical role. The key factors involved while selecting the most appropriate material are properties and functions of material, manufacturability, cost, failure mode, and environmental considerations. In general, all such factors are arranged in groups of material properties known as Material Indices (MIs) as given in 1below. The form of the MI depends on the functional requirements of an object and its geometry. In the material selecting procedure material properties including cost are compared and a material having higher MI is selected to use in manufacturing the specific object.
Forgiven case similar approach can be applied to select an appropriate light reasonable material that can be used to manufacture the intermediate case in Trent- 900 Gas Turbine Engine. Comparing the properties of various materials given in table 1 then.
1) For material having the best performance in terms of Young’s modulus to density ratio comparing the material properties given in 4 and 5 as given in table 1 when comparing the properties of various metals and Composite Fiber Reinforced Polymers (CFRP) – the best-suited material for intermediate case in Trent- 900 Gas Turbine Engine, the lightest appropriate material having least value of density (ρ, Mg/m3) is CFRP Laminate (graphite) hence it is the best light material in terms of Young’s modulus to density i.e.
Again comparing Young’s modulus to the cost-density ratio the best material for the intermediate case in Trent- 900 Gas Turbine Engine is Aluminum alloy (7075- T6) as compared to composite and metal it quite cheaper (1.8 $/kg) with lightweight. .
