Rationale for objectives
At some stage in their careers, all engineers will need
to chose materials, and processes to shape and join
them.
This unit is intended to give you some insightinto that
process.
It will not solve all your material selection problems,
but will set you on the way to solving those problems(lay the foundation).

To introduce you to Materials Engineering from the
point of view of selection of materials and materials'
usage.
To demonstrate that all engineers need to understand

Assessment Guide
Unit Guide has broad objectives
I will start each lecture with a series of typicalassessment points. These are the things you shouldexpect to be examined on
For example:
Identify the property which governs the choice ofmaterial for a given application (e.g., bike forks, bridge,spring, drive shaft, ship hull...)
Describe the features of a material which control agiven property (strength, hardness...)

The RAPID FEEDBACK QUIZ
Approximately every 3-4 lectures I shall collect your
(anonymous) written responses to the following
statements, and these will be used to set the agenda
for the tutorials. Be prepared to discuss the issues at
the tutorial. The information is also valuable feedback
for me.

PlagiarismPlagiarism is the presentation of another persons work, ideas or creations under your own name,
acknowledging where that work came from.
Monash University policy on plagiarismAll work submitted for assessment must be the studentsown work. Sources of the work of others mbe acknowledged in full. Plagiarism is an attempt to obtain undeserved academic advantage. Studsuspected of plagiarism will be given the opportunity to explain their plagiarism in the company of lecturer and the course coordinator. If the chief examiner believes that plagiarism has occustudents will normally receive no marks at all for the piece of work concerned. Cases of delibeplagiarism will be dealt with in accordance with the UniversitysDiscipline Statute 4.1.

In your assignments
you must alwaysacknowledge anytype of contento datao factual informationo opinionso ideaso tables & graphso imageso

Ma
which you obtain from other sources
o textbookso journalso reportso
theseso websiteso conference paperso course notes
with an in-text citation and reference list entry.
If you have used anyone elses work without acknowledgingthe source, you have plagiarised.

Plagiarism includes:Copying or cutting-and-pasting:
text word-for-word without quotation marks and reference to the author - paragraphs,
sentences, or phrases anypart of another students work including images, graphs, tables and calculations
Submitting: work that has already been submitted for assessment in another course or unit - including your
own work work under your own name that someone else has done for you
How to avoid plagiarism:
If you include anyinformation or other content that you did not create yourself, you must acknowledge it with ancitation and reference list entry.
Never write an assignment with source material open in front of you: write from your own notes.
Alwaysrecord the source of information, ideas, data, figures, images you intend to use in an assignment.
UseTurnitin.

What is Turnitin?
Turnitin is text-matching softwareto assist students and staff in understanding and supporting the eand appropriate use of materials. The software was introduced by the University in late 2013 and willused for the first time University wide in semester one 2014. Turnitin will be integrated into the assignmodule in Moodle. This means that assignments that use Turnitin will be set up a bit differently than Massignments in the past. Learn how to set up a Turnitin assignment in Moodle.
How does Turnitin work?
Assignments are submitted via Turnitin in Moodle
The software compares the assignment text to a database of more than 12 billion pages of digital co
The software outputs a similarity report (for lecturers) indicating sections of the assignment that matin the database

Turnitinwhats in it for students?
If made available for the unit: students may:
1.Submit a draft of their work via the assignment submission link
2.Check the similarity of their work with the existing turnitin database (A similarity report will be generated and be downloaded by the student).
3.Resubmit their final work for assessment by re-uploading the assignment to the submission link.
Limitations:
1.Students may only check their assignment once every 24 hours
2.The system will only consider similarity against pre-existing work in the turnitin database it will not comparefrom one student to the other in the same class. However, when the academic runs the final report, there will bcheck made both with the pre-existing database and with all of the submissions of the class.
3.A student who wishes to compare their draft work with the database needs to be aware that once the submisdeadline has passed, their draft would be taken as their final submission. Students are responsible to ensure th
their final submission is uploaded priorto the submission deadline.

Poor note taking can lead to plagiarism Record publication details first: author, title, year, journal, publisher, url
When making a note:
summarisethe point in your mind first write without looking at the source material go back to the source to checkspelling, numerical values, etc
When writing notes, do not include the grammar; use diagrams, symbols and abbreviations
show meaning.
Mark any word-for-word copies with quotation marks and note the page number.
Clearly distinguish your own ideas from ideas of other authors and researchers.
Beware the paraphrasing trap Making small changes to the original vocabulary, sentence structure or paragraph structure is
plagiarism it is too close to the original.
Write whatYOUwant to say inYOURown way fromYOURnotes.
Cite the source of the information or idea.
