Module Aims

To develop an understanding of the deformation and failure behaviour of simple structural components subjected to force, torque and other physical effects.To introduce complex stress, strain and failure characteristics.

Learning Outcomes

On completion of this module, the student will be able to:

· Apply conventional engineering terminology and nomenclature to simple material mechanics problems. (PO1, PO6)

• Devise an appropriate calculation from a narrative describing component loading and geometry. (PO1,PO2,PO3,PO6)

• Calculate stress and strain in simple components under axial, bending, torsion or pressure loading.(PO1,PO2)

• Explain Mohr’s circle and apply it to 2-D problems. (PO1,PO2,PO6)

• Describe methods of strain measurement, their limitations and advantages. (PO1,PO6)

Teaching & Learning Strategies/Assessment Methodology:

Lectures are used to teach principles, illustrating these with examples. Modules notes with some missing detail and space for note taking in class are made available. Assisted tutorials provide an opportunity for learners to apply knowledge and practice calculations.

Laboratory work includes both individual and group exercises, and requires oral and written reports. Oral reports with immediate constructive feedback take place early in the semester. They are particularly useful to teach analysis and interpretation of data. They also help to learners gain confidence in their ability to communicate technical ideas and concepts orally.
