Module Description: Describes the properties of a range of materials and explains their behaviour based on the underlying principles of physics.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Interpret basic empirical data regarding material properties and consequently predict material behaviour.
LO2 Describe and evaluate material strengthening/hardening and destructive/non-destructive testing methods for particular materials.
LO3 Describe materials, process attributes and design requirements for particular applications.
LO4 Determine the sustainability of processes used to manufacture and reuse materials.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed

Requirements

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
