| Teaching & Learning Strategies: |
The module will be delivered using lectures, tutorials and laboratory sessions. |
| Module Aim: |
To provide the students with the knowledge and skills required for evaluate a range of structures under complex loading condition by analytical and numerical analysis. |
| Learning Outcomes |
| On successful completion of this module the learner should be able to: |
| LO1 |
Analyse complex stresses and strains due to combined loading and loading on oblique plains. |
| LO2 |
Plot the stresses and strains at any plane across the field using graphical methods such as Mohr’s circle. |
| LO3 |
Apply the theories of elastic failures to composite structures and assymmetric beams. |
| LO4 |
Execute the mathematical and physical principles underlying linear static structural Finite Element Analysis (FEA). |
| LO5 |
Analyse complex structural problems using commercial FEA software packages. Demonstrate the ability to design a component/assembly and carry out bolted joint analysis using FEA |
| LO6 |
Contribute effectively, as an individual or as part of a group, to the planning and realization of investigations in a laboratory environment into the behaviour of structural materials in service. |
