Aims |
|
To provide an introduction to the mathematical theory of viscous fluid flows and solid elastic materials. Cartesian tensors are first introduced. This is followed by modelling of the mechanics of continuous media. The module includes particular examples of the flow of a viscous fluid as well as a variety of problems of linear elasticity. |
Learning Outcomes |
|
(LO1) To understand and actively use the basic concepts of continuum mechanics such as stress, deformation and constitutive relations. |
|
(LO2) To apply mathematical methods for analysis of problems involving the flow of viscous fluid or behaviour of solid elastic materials. |
|
(S1) Problem solving skills |
|
(S2) Numeracy |
|
(S3) Adaptability |
