This subject consists of two distinct and fundamentally related topics -

• An introduction to the fundamentals of materials science will be given on atomic structure and bonding, crystal structures and defects, elastic and plastic deformation, dislocations and strengthening and failured (fast fracture, fatigue and creep).
• The mechanics of materials section will extend the concepts of material mechanical behaviour by detailing elastic/inelastic behaviour and introducing the concepts of stress and strain analysis.Topics covered may include the definition of principal stresses, plane stress, plane strain, two-dimensional stress and strain analysis, torsion, pure bending, transverse loading, Mohr’s circle, failure criteria, inelastic behaviour, residual stress.

Particular emphasis will be placed on the fundamental mechanisms by which materials fail under loading.

At the conclusion of this subject students should be able to -

• Perform basic stress and strain analysis
• Analyse mechanical behaviour of materials
• Obtain simple mathematical and physical relationships between mechanics and materials
• Describe various testing techniques for characterisation of mechanical behaviour of materials

• One three-hour end of semester written examination (70%)
• Three laboratory sessions with reports and 1 assignment (30% total) during the semester. Attendance at the labs and submission of written lab reports are compulsory to pass the subject.

Materials Science and Engineering – an Introduction by W. D. Callister, Jr.

This subject potentially can be taken as a breadth subject component for the following courses:

• Bachelor of Arts
• Bachelor of Commerce

You should visit learn more about breadth subjects and read the breadth requirements for your degree, and should discuss your choice with your student adviser, before deciding on your subjects.

On completion of this subject, students should have developed the following generic skills -

• Ability to apply knowledge of science and engineering fundamentals
• Ability to undertake problem identification, formulation, and solution
• Ability to utilise a systems approach to complex problems and to design and operational performance
• Ability to communicate effectively, with the engineering team and with the community at large
