Unit description Unit description
The purpose of this unit is to develop an understanding and insight into the design and utilisation of engineering materials; these materials include metals, polymers, ceramics, and composites. Students will develop knowledge of the mechanical properties of different materials in relations to the physical and chemical phenomenon. Topics covered in this unit will include physical and chemical nature of materials, the effects of nano-, micro- and macro- structures in material properties, considerations in modifying mechanical properties in metallic systems, composite design and materials selection.
