### Description

This course follows on from Mechanics of Solids 1 to provide a more advanced treatment of solids mechanics and elasticity theory. This material is covered alongside a practical introduction to the Finite Element Method and instruction in a commercial software package. Comparisons between analytical and computational approaches will be drawn.

### Learning outcomes

On successful completion of the course students will be able to:

1. Demonstrate a sound understanding of the transformation of stress.

2. Apply analysis techniques to determine stress in thin-walled non-circular sections subject to torsion and to locate the shear centre in thin-walled beams.

3. Demonstrate an understanding of elasticity theory for beams and plates and the respective finite element approximation.

4. Demonstrate a sound understanding of the Finite Element Method as applied to linear static analysis and natural frequencies of vibration.

5. Successfully build finite element models using a commercially-available finite element software package, undertake linear static and natural frequency analyses and interpret the results.

### Content

1. 3D stress fields, transformation of stress and stress invariants.
2. 2D and 3D Mohr circle.
3. Torsion of thin-wall non-circular cross-sections.
4. Shear centres of beams.
5. Introduction to the finite element method including solving linear static problems with spring and bar-element systems.
6. Theoretical linear static behaviour of bar, beam and two-dimensional elements and predictions using the finite element method.
7. Natural frequency analysis using the finite element method
8. Introduction to a commercially available finite element package to solve linear static problems and determine natural frequencies of vibration.
