Synopsis
Key concepts in the design, selection and application of materials. Attributes such as stiffness (modulus), strength, toughness, chemical stability, electrical, magnetic, and thermal properties will be explained in terms of atomic bonding, crystal defects, polycrystalline microstructure and material flaws. Case studies will include a broad range of materials such as carbon nano tubes, microchips, reinforced concrete, biomaterials, suspension bridge, and aerospace components, all used in a diverse range of engineering applications.
Objectives
On successful completion of this unit students will:
- appreciate the influence of atomic structure, bonding and nano/microstructures have on some physical properties
- have an understanding of different materials responses to forces and stresses
- have an understanding of the basic mechanical properties, principally elastic modulus and yield stress, and be able to use these as design criteria
- be familiar with processes occurring during plastic deformation and to draw upon these concepts in order to know how to strengthen the material
- know how to tailor the mechanical properties of a polymeric material using control over crystallinity and the glass transition
- understand the role of composite materials in engineering, and their responses to applied stresses
- understand the processes involved during fracture and have a broad understanding of how fracture can be avoided by appropriate selection of materials and design
- have a basic understanding of the thermal, electrical and magnetic properties of materials in terms of the atomic and electronic characteristics of materials and to use these criteria for material selection
- understand the processes of corrosion and degradation in the environment and to draw upon these to increase the lifetime through appropriate protection and material selection
- be able to select an appropriate material for a given application based on the above points
- appreciate the socio-political and sustainability issues influencing material selection, commonly experienced as a professional engineer
- have become familiar with the resources of a library for acquiring information of specific interest to a materials engineer
- have gained basic laboratory skills applied to study the microstructure and physical properties of materials;
- have an ability to communicate within a team in carrying out laboratory work
- have an ability to keep accurate laboratory records and to prepare a formal report on an experiment.
