DESCRIPTION - summary of the module content

In this module you will learn about the fundamental theories governing elasticity in solids, and the methods engineers use to measure these properties in real world problems. One simple example of this; the stress concentration around a hole in a plate is examined in detail in a lab class. This module will give you the knowledge and skills to calculate what these stresses are, measure them in a lab or in service, understand how to analyse such data, and to design components to avoid such issues in the first place. This will help prepare you for similar complex problems in professional practice.

AIMS - intentions of the module

This module introduces you to more advanced aspects of theory of elasticity, as applied to solid mechanics. This provides a solid basis for the study of Solid Mechanics, Computational Engineering and Materials. Furthermore, the module introduces and develops experimental stress analysis, techniques for global and localised strain and stress measurement, and data analysis. Finally, it applies these to study of fracture and failure behaviour of materials and in the application of analytical techniques to problems of fracture mechanics.

 

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module, you should be able to:

Module Specific Skills and Knowledge:

1 understand the physical concepts of stress and strain in tensorial form, demonstrate familiarity with the stress and strain patterns for certain canonical stress problems, derive principle stresses and strains for 2D and 3D elasticity problems;

2 comprehend and apply the mathematical techniques, (eg. Stress Functions) used to derive analytical solutions for these cases;

3 show familiarity with the range of experimental stress analysis techniques, their fundamental principles, application and limitations, select techniques appropriately, critically evaluate experimental data in the light of theoretical analysis and apply this to component design;

Discipline Specific Skills and Knowledge:

4 apply mathematical theory to experimental data and critically evaluate both this data and theoretical limitations;

5 display enhanced skills in determining appropriate theoretical and experimental techniques for problems;

6 demonstrate improved ability to use computational methods to model engineering problems.


Personal and Key Transferable/ Employment Skills and Knowledge:

7 reveal a high level of proficiency in analysing information;

8 exemplify excellent organisational and time management skills, and the ability to learn independently, through planning your own work;

9 prove strong communication skills, through presenting your work orally and in writing.
