|Description || The aim of the module is to introduce the range of materials and their key properties used in engineering in order to allow them to select the appropriate materials for a given application. The module also introduces fundamental science that determines the electrical or mechanical properties of materials, such as atomic / molecular structures. In addition students will also be introduced to software which will allow them to model the properties and behaviour of engineering materials and analyse the results of experiments.|
