The objective in presenting this unit is to impart to students the key components of study into the strength of materials, particularly the mechanics of structures and stress analysis, with an emphasis on advanced topics and analysis.

 

The subject matter covered in this unit will include: mathematical models used to describe the effects of forces on simple structures under combined actions; the concepts of stress and strain transformation, Mohr circles and combined stresses and aspects of stability.

 

At the conclusion of this unit, students will have acquired the requisite specialised knowledge to undertake the design and analysis of many different structures. Futhermore, the acquisition of the information from this unit will provide students with a basis on which more advanced forms of analysis and design skills can be further developed in later units.

On successful completion of this Unit, students are expected to be able to:

1. Design structures for axial loads and direct shear and analyse shear stress in simple beams.

2. Determine, assess and validate beam deflections and bending stresses/strains in composite beams.

3. Design, analyse and interpret combined stresses in simple structures

4. Design and specify simple column analysis and interpret results to provide solutions to specific problems.
