Text book: There is no specific textbook suggested for this course, but a series of books and articles are consulted for lecture materials.
Since a wide range of topics covered, there is not any textbook or specified reference book, but the following books, articles, internet websites (pictures and diagrams) were consulted in conjunction with the Lecturer’s own experience over the last thirty years to prepare the overheads. However, the Book by Prof. M.F. Ashby (Materials selection in Mechanical Design) is particularly a useful book for this course and is recommended as a useful addition to your personal library as it contains a large amount of data on materials and their applications in mechanical design.

Learning & Teaching Activities
Learning & Teaching Modes
Teaching and learning modes for this course are through contact lectures, tutorials, case studies and mini projects. The lectures provide the background theory for the subject, while the tutorial and case studies give students hands-on experience on materials selection and failure analysis. For the mini projects, the students learn how to implement the gained knowledge in manufacturing engineering components through appropriate selection of materials and manufacturing processes. The tutorial questions are expected to be answered by the students before the tutorial sessions (all marked as part of assignment) where the answers and explanations will be provided by the Tutor/Lecturer.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.
Lecture Contact Hours: 24 hours Tutorial Contact Hours: 24 hours Assignments: 24 hours Mini Projects 24 hours Exam Preparation: 34 hours Total: 130 hours
Learning Activities Summary
To introduce students to various tools that can be used to select the appropriate material for a given application.
Examination of various failure modes to allow students to identify these modes in real samples
Apply material selection and failure analysis techniques to failure prevention,
Content: The concept of Materials Selection and Failure Analysis is an important issue in engineering design and fabrication, since on one hand the application of proper procedure for materials and process selection guarantees the production of sound and reliable engineering artefacts and on the other hand provides insights as why and how an engineering part has failed. The latter helps to identify the short comings of as-manufactured components and provide guidelines to avoid or mitigate future failures.
For engineers to be able to implement the proper procedure for materials and process selection, they require to have a broad knowledge of materials properties and manufacturing techniques. Therefore, the current lectures are designed to provide such broad knowledge and cover the following topics;1- An introduction to design2- Engineering Materials and manufacturing processes3- Mechanical properties of materials4- Ductile and Brittle fractures5- Fatigue6- Creep7- Wear8- Corrosion9- Materials selection procedures and methods10- Effect of shape on materials selection11- Materials Processing selection12- Environmental/energy consumption issues13- Failure analysis of engineering parts14- Failure analysis-case studies15- Revision-Summary
The above-mentioned topics are presented as overheads covering the main points while the details will be discussed during the lectures.
Specific Course Requirements
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
The following is an outline of the assessment for this course. Please note that while every effort has been made to ensure that this information reflects an accurate plan, the coordinator reserves the right to make changes that ensure the continual improvement of the course. Any such changes will be made clear during the lectures and via MyUni.

The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
