Electrical and Mechanical Materials

Module overview

This module equips students with a comprehensive understanding of how mechanical systems move and deform when subjected to external forces. We then progress to advanced topics including buckling and deformation of mechanical structures such as beams and cantilevers. The second part of the module covers materials response to applied electric and magnetic fields, e.g. polarisation and conduction in dielectrics, magnetisation and ferromagnetism. Materials for novel and emerging applications are considered as well, e.g. high-voltage cable insulations, electret materials, triboelectric series, piezo-electricity, ferro-electricity, pyroelectricity. The module includes one laboratory analysis covering dielectric material characterisation and one laboratory experiments on deformation of beams. Students will be supported by examples and tutorial questions with many real-life practical examples.

Learning and Teaching

Teaching and learning methods

The content of this module is delivered through lectures, module website, directed reading, pre-recorded materials and tutorials. Students work on their understanding through a combination of independent study, preparation for timetabled activities, tutorials and problem classes, along with laboratories. Students work on their practical skills and technical understanding in technical laboratories.
