Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Attribute Development Method Attribute Developed
From previous studies, students are expected to appreciate implicit solution methods and their limitations in highly non-linear applications. The use of explicit methods is encouraged for solving non-linear problems. Students work in very small groups to provide peer tutoring throughout the course. (2) Engineering/ IT Specialisation (Level 5)
Students use a combination of CAD and a FEA Pre-Processor to construct models which they have designed. The designs are then solved using LS-DYNA and assesed for suitability in highly non-linear applications. Students develop smaller models individually as part of a very small group where each member contributes to the final design and it solution. (4) Design (Level 4)
Students communicate their work via; individual assignments, group presentation and in a group capstone project which encourages collaboration with fellow students and deeper examination of their topic. (6) Communication and Inquiry/ Research (Level 2)

For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table 2018.

Assessment Description: * indicates an assessment task which must be repeated if a student misses it due to special consideration.

Assessment:

Assessment is by way of group assignments which necessitate the use of high end PCs to design crash or multi-physics scenarios. Extensive reading of supplied literature is required for comprehensive understanding of the subject material.

Assignments:

Assignment 1 is assessed as a written report that examines a group`s ability to demonstrate effective use of a Pre-Processor, Solver and Post- Processor. The focus of the report is to be focused on a typical crash scenario.

Assignment 2 is assessed as a written report that examines a group`s ability to demonstrate effective use of a Pre-Processor, Solver and Post- Processor.

Quizzes:

Two closed-book quizzes which test a student`s knowledge on the subject matter as is progressively covered in lectures and in expected private readings.

Project:

A group Project that focuses on bringing individual skills together in an FEA capstone project involving either a large multi-body crash-simulation or a simulation incorporating multi-physics.

Assessment is by way of a presentation and group report.

Minimum performance criteria:

1. You must get a minimum average mark of 40% in the Quizzes to pass the unit, regardless of the sum of your individual marks.

2. There may be statistically defensible moderation when combining the marks from each component to ensure consistency of marking between markers, and alignment of final grades with unit outcomes.

3. The penalty for lateness is in line with current university guidelines.

All Assignments and Project will be submitted online through CANVAS and scanned for plagiarism using Turnitin.
Assessment Feedback: Assessment feedback is by way of written comments on a marking sheet or via CANVAS. Feedback will be provided within two weeks of assessment submission.
Feedback will also be provided during the lecture and as needed face-to-face.
Grading:
Grade Type Description
Standards Based Assessment Final grades in this unit are awarded at levels of HD for High Distinction, DI (previously D) for Distinction, CR for Credit, PS (previously P) for Pass and FA (previously F) for Fail as defined by University of Sydney Assessment Policy. Details of the Assessment Policy are available on the Policies website at http://sydney.edu.au/policies . Standards for grades in individual assessment tasks and the summative method for obtaining a final mark in the unit will be set out in a marking guide supplied by the unit coordinator.
Policies & Procedures: See the policies page of the faculty website at http://sydney.edu.au/engineering/student-policies/ for information regarding university policies and local provisions and procedures within the Faculty of Engineering and Information Technologies.
Recommended Reference/s: Note: References are provided for guidance purposes only. Students are advised to consult these books in the university library. Purchase is not required.
Note on Resources: All reading resources will be made available directly by printed notes, pdfs or WEB links by the course coordinator.
