Description including Unit Aims
This course is split into two main sections: properties of materials and mechanics of materials.
Mechanics of Materials: presents the advanced principles of elastic analysis in three dimensions, and applies these concepts to idealised problems based on simple engineering structures. Specific topics covered 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.
Properties of Materials: This section of the course covers three main themes: 1) fatigue analysis and prediction in uncracked bodies, 2) advanced material selection strategies when conflicting objectives are required and 3) the production of metals and their thermomechanical processing. Specific aims of the course are
- Demonstrate how basic mechanics and S-N curves can be used to predict fatigue lifetimes in uncracked components.
- Develop strategies within the Ashby method for choosing appropriate materials when there are conflicting objectives or multiple coupled constraints.
- Show how material structures depend on temperature and how this can be determined from a phase diagram
Demonstrate how the physics of transformations dictates the heat treatments used in industry and how this alters material properties. There is a focus on steel and related engineering alloys.
Intended Learning Outcomes
- Be able to anticipate and predict fatigue failures in uncracked components
- 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
- Be able to create thermomechanical production processes for steel and diagnose the causes of failure in steel components
- Able to solve a wide range of problems in Mechanics of Materials by using suitable theoretical methods.
- Able to demonstrate the modelling skills needed to simplify complex mechanics of materials problems such that efficient analysis may be carried out.
- Able to specify the assumptions made in modelling and the likely accuracy of calculated results.
- Use precise, accurate written language.
Teaching Information
