Module title:Mechanics of Materials
Module codeECMM107
Module lecturers:Prof Christopher Smith
Module credits:15

In this module you will learn about i) the theory of elasticity and specifically application of it using a tensor approach to tackle more advanced problems, ii) experimental stress analysis techniques to measure strains and stress in components, and iii) about failure and fracture of solids, and the methods engineers use to predict these.

An example could be a component with manufacturing defects which give rise to unexpected stress concentrations. This module will give you the knowledge and skills to calculate what these stresses are, measure them in a real component, and to re-design the component to avoid such issues. This will help prepare you for similar complex problems in professional practice, often involving measurement of stress on real components and computational modelling.

Firstly it extends students’ knowledge of elasticity towards more advanced aspects, and takes a tensorial approach as is often required in solid mechanics. The theory of elasticity and its use in tensorial form, underlies many aspects of modern engineering practice, for instance in the simulation of static and dynamic responses of components and structures in Finite Element Analysis. Professional standards of practice almost always require use of elasticity to predict the behaviour of safety critical components. This part provides a solid basis for further study of Solid Mechanics, Computational Engineering and Materials.

The module then moves on to introduce and develop experimental stress analysis techniques. It starts with a review of the physics behind a range of modern techniques, identifying how these make them suitable or unsuitable for different applications. It goes on to apply some techniques, e.g. foil resistance strain gauges, to the classic problem of a flat plate with a circular hole in a laboratory session.

In the third section it extends knowledge form earlier modules failure and fracture behaviour of materials, and particularly on analytical techniques to predict such problems. This includes laboratory demonstrations of failure/fracture and use of Finite element methods to simulate such responses.
