Brief Description (including aims of the course):
The first part of this module introduces the idea of materials selection using Ashby diagrams. The importance of different material properties (strength, density, melting point) will be considered. This will lead to a discussion of various methods of processing and the reasons for different processing technologies and will also compare (cost, environmental implications) of different processing routes, including new/innovative processing. The relation between properties, product performance and processing will be emphasised. The second part of the module introduces the mechanics and microstructures of materials with reference to aerospace applications including: (1) Meaning of stress and strain, Mohr's circle, test methods and analysis (2) Importance of length-scales: macro, meso and atomic (3) Metallic crystal structures; defects and dislocations; grain boundaries (4) Links between microstructures and material properties.
This unit aims to:
•Introduce students to basic ideas in mechanics of materials;
•Show how and why different materials have different mechanical behaviours;
•Illustrate the consequences of this for materials selection;
•Give students an understanding of why particular materials are chosen for particular tasks;
•Give students an understanding of why a particular process route is chosen for a given application.
Course Objectives:
By the end of this course, you should be able to:
•Demonstrate an understanding of the relationships between the microscopic and macroscopic mechanical
properties and behaviour of materials;
•Undertake quantitative calculations involving the mechanical properties and behaviour of materials;
•Explain the fundamental concepts underlying Ashby charts and use such a chart to select a material for a simple application;
•Discuss different processing routes for selected materials and link the choice of processing route to particular applications;
•Understand the importance of materials selection in product design.
