Description

The objective of this second year course is to build on the first year course by introducing a number of more advanced topics. Properties of Materials: Presents more advanced material properties including fatigue and corrosion behaviour of metallic systems. The mitigation of these common failure routes will be explained and students will be able to making working estimates of likely material lifetimes. Students will learn more advanced materials selection strategies in order to deal with conflicting or differently weighted objectives. The possibilities of manipulating material properties via thermomechanical processing will be discussed, via phase diagrams and transformation curves, in order to impart a working knowledge of common alloy systems. An emphasis is placed on the Fe-C system given its importance to engineers. Mechanics of Materials: 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

Intended learning outcomes

Properties of Materials:

  • Be able to anticipate and predict fatigue and corrosion failures
  • Use rational strategies to select materials in the face of conflicting requirements
  • Be able to read phase diagrams and so anticipate the likely structure of materials
  • Understand how temperature effects the kinetics of reactions
  • A strong working knowledge of the steel system and how it obtains its properties

Mechanics of Materials:

  • The ability to analyse a wide range of problems in Mechanics of Materials by using suitable theoretical methods.
  • To develop the modelling skills needed to simplify complex mechanics of materials problems such that efficient analysis may be carried out.
  • To appreciate the assumptions made in modelling and the likely accuracy of calculated results.

Teaching details

  • 22 lectures of duration 50 minutes
  • 1 Lab
  • 1 materials selection group project

Mechanics of Materials:
