Description including Unit Aims

Mechanics of Materials:This course seeks to give students the skills and knowledge required to analyse a wide range of topics in Mechanics of Materials, and to give them a sound foundation on which to build future work. Properties of Materials:This course seeks to give students a conceptual understanding rather than a liturgy of rules, lists and numbers. It begins with a detailed study of fatigue and its failures. Students are given a comprehensive insight into the mysteries of the common alloy systems including irons and steels, stainless steels, copper alloys and aluminium alloys. The aim is to predict properties of alloys via their phase diagrams.

Aims:

The objective of this second year course is to build on the first year course by introducing a number of more advanced topics. For Mechanics of Materials, these will include non-symmetric bending of beams, thick walled cylinders, yield criteria, torsion of non-circular sections, buckling, energy methods, rotational stresses and bending of plates. Students should gain an understanding of the assumptions made in the various theoretical models employed and thus their limitations.

With respect to properties of materials, students will acquire a working knowledge of fatigue and fatigue failure. They will be able to assess failures and categorise these in terms of overload, fatigue, corrosion, etc. They will acquire a rigorous, in depth understanding of the common alloy systems they are likely to encounter in their engineering careers. These systems include irons and steels, stainless steels, copper alloys, aluminium alloys etc. Discussion of these alloy systems is based on the materials fundamentals taught in the first year unit.

Intended Learning Outcomes

1. The ability to analyse a wide range of problems in Mechanics of Materials by using suitable theoretical methods.
2. To develop the modelling skills needed to simplify complex mechanics of materials problems such that efficient analysis may be carried out.
3. To appreciate the assumptions made in modelling and the likely accuracy of calculated results.
4. Students will be capable of entering any field of engineering with sufficient materials background such that they would feel competent to make judgements and discuss the merits, or otherwise, of various materials options.
5. The students will also have sufficient knowledge relating to engineering alloys for study at higher degree level.
