Aims & Objectives:

Aims of the course can be identified as follows:

To develop an awareness within students of the correlation between the structure of materials at the nano, micro and macro level and the properties of the three major classes of materials, namely, metals, polymers and ceramics
On the basis of structure/properties correlations, introduce students to the concepts involved in the designing the structure of a material to achieve a predetermined set of properties
To demonstrate and explore through the use of practical laboratory experience the structure/property relations of materials and their effect on performance
To provide students with the opportunity to work in small groups and carry out a research project in which they determine the structure/property relations of materials used in well known products, and present their findings in peer reviewed oral presentations
To make students aware of failure in materials and thereby develop an understanding of the principles of materials selection
Focus student awareness on the fact that many materials are derived from nonrenewable sources and suffer from degradation in many forms in their application. Hence, bring students to the realisation that materials and technology can cost-effectively contribute to building an ecologically friendly and sustainable environment
Excite students in the knowledge that advances in modern materials are playing critical roles in many new technologies

At the completion of this unit, students should be able to:

Describe the difference in atomic/molecular structure between the major classes of materials that give rise to differences in material properties
To analyse material response to mechanical and physical stimuli
Compute mechanical properties of all major classes of materials on the basis of experiment
Use mathematical knowledge and skills to calculate basic physical properties of materials
Ability to comment, particularly at the design and selection stage, on the suitability of different methods of strengthening of materials and the potential for material degradation
Possess a basic methodology for materials selection in respect of the method of manufacture and its influence on structure/properties and anticipated performance, and the potential for recyclability

Teaching Methods:

Lectures; Tutorials; Laboratory;Online

Assessment:

Examinations (50% - 80%), Assignments and Labs (20% – 50%)
Actual allocation of marks will be specified in the Unit of Study Outline.

Generic Skills Outcomes:

Students are expected to enhance several of their graduate attributes during this unit
and should consult with your lecturer if not clear as to how this unit achieves this. The
graduate attributes which relate to this unit help to produce students who are:

Are capable in their chosen professional, vocational or study areas
Operate effectively in work and community situations
Are aware of environments in which they will be contributing

In addition to the Swinburne generic attributes, this subject is also expected to enhance
skills recognised by the Institution of Engineers (Australia), specifically:

Ability to apply knowledge of basic science and engineering fundamentals
In-depth technical competence in at least one engineering discipline
Ability to understand problem identification, formulation and solution
Ability to utilise a systems approach to design and operational performance
Ability to function effectively as an individual and in multi-disciplinary and multicultural teams, with the capacity to be a leader or manager as well as an effective team member
Understanding of the social, cultural, global and environmental responsibilities of the professional engineer, and the need for sustainable development
Understanding of the principles of sustainable design and development
