AMME5912: Crash Analysis and Design

Semester 1, 2023 [Normal day] - Camperdown/Darlington, Sydney

The objective of the course is to give students skills in the area of highly non-linear finite element analysis. Major topics covered include CAD, Implicit / explicit codes, Wire frame geometry, Elemental Theory, Materials, Pre-processing using ETA-PreSys, Contact, LS-Dyna, using NCAC FEM models, Modeling fasteners and the interaction between solids and fluids. Material covered in lectures is reinforced through independent research, assignments, quizzes and a major capstone project. The capstone project involves the development of an approved crash scenario.

Assessment summary

  • Assignment 1: Assignment 1 is assessed as a written report that examines an individual student’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: Assignment 2 is assessed as a written report that examines an individual student’s ability to demonstrate effective use of a pre-processor, solver and post-processor.
  • Assignment 3: Assignment 3 is assessed as a written report that examines an individual student’s ability to demonstrate effective use of a pre-processor, solver and post-processor.
  • Project and group presentation: 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.
Detailed information for each assessment can be found on Canvas.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name

Mark range

Description

High distinction

85 - 100

Awarded when students demonstrate the learning outcomes for the unit at an exceptional standard.

Distinction

75 - 84

Awarded when students demonstrate the learning outcomes for the unit at a very high standard.

Credit

65 - 74

Awarded when students demonstrate the learning outcomes for the unit at a high standard.

Pass

50 - 64

Awarded when students demonstrate the learning outcomes for the unit at an acceptable standard.

Fail

0 - 49

Awarded when students do not meet the learning outcomes of the unit to a satisfactory standard.

For more information see sydney.edu.au/students/guide-to-grades.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

All group assessments require you to review your performance and that of your team members using SPARKPLUS.

Individual marks for group assessments will be adjusted based on these reviews.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

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

  • LO1. Present findings and results by way of producing a written capstone project at near publication quality.
  • LO2. Visually present and defend findings and results by way of a group presentation or audio embedded Powerpoint presentation.
  • LO3. Develop competentcy in the use of CAD to develop FEA models
  • LO4. Develop skills using a pre/post processor to mesh and apply boundary conditions to an FEA model.
  • LO5. Introduce predefined small FEA automotive models and develop these into a defined virtual environment.
  • LO6. Develop skills in editing and interpreting an LS-DYNA deck and output files.
  • LO7. Develop and master skills in selecting the correct element type when developing an FEA model.
  • LO8. Develop skills in the correct material model when developing an FEA scenario.
  • LO9. Develop skills in the correct contact method when developing an FEA model.

Graduate qualities

The graduate qualities are the qualities and skills that all University of Sydney graduates must demonstrate on successful completion of an award course. As a future Sydney graduate, the set of qualities have been designed to equip you for the contemporary world.

GQ1 Depth of disciplinary expertise

Deep disciplinary expertise is the ability to integrate and rigorously apply knowledge, understanding and skills of a recognised discipline defined by scholarly activity, as well as familiarity with evolving practice of the discipline.

GQ2 Critical thinking and problem solving

Critical thinking and problem solving are the questioning of ideas, evidence and assumptions in order to propose and evaluate hypotheses or alternative arguments before formulating a conclusion or a solution to an identified problem.

GQ3 Oral and written communication

Effective communication, in both oral and written form, is the clear exchange of meaning in a manner that is appropriate to audience and context.

GQ5 Inventiveness

Generating novel ideas and solutions.

GQ6 Cultural competence

Cultural Competence is the ability to actively, ethically, respectfully, and successfully engage across and between cultures. In the Australian context, this includes and celebrates Aboriginal and Torres Strait Islander cultures, knowledge systems, and a mature understanding of contemporary issues.

GQ7 Interdisciplinary effectiveness

Interdisciplinary effectiveness is the integration and synthesis of multiple viewpoints and practices, working effectively across disciplinary boundaries.

GQ8 Integrated professional, ethical, and personal identity
