MECH ENG 4118 - Finite Element Analysis of Structures

North Terrace Campus - Semester 1 - 2016

The course information on this page is being finalised for 2016. Please check again before classes commence.

The course will equip students with the necessary knowledge to use finite element analysis to solve problems related to solid mechanics, dynamics, heat-transfer and acoustics. FEA is a design/research tool that is extensively used in industry and research institutions. Students will also gain hands-on experience in using finite element analysis software ANSYS to solve realistic engineering problems.

  • Learning & Teaching Activities
    Learning & Teaching Modes

    Teaching and learning modes for this course are through contact lectures, computer laboratories in the Computer Aided Teaching Suites (CATS), self-study, and a project using finite element analysis software. The lectures provide the background theory for the subject, and the computer laboratories provide learners with the practical experience in using Finite Element Analysis software to solve engineering problems. The FEA Project is an integral part of the course learning and outcomes, and is used to develop the graduate attributes of the learners. The FEA project enables Learners to demonstrate their knowledge gained from the course by independently solving a complex engineering problem. Online quizzes are a formative part of the learning experience and provide learners with the ability to demonstrate their understanding of the course material.

  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

    Assessment Summary

    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.

    Component Weighting Learning Outcome

    Final Exam 60% 1-7
    Assessment Related Requirements

    Completion of the FEA Project with a grading of Pass or higher is required.

    Assessment Detail

    The online quizzes comprise multiple choice answers, and some short descriptive answers. The online quizzes are to be submitted before the commencement of the following lecture, where the answers will be provided. Late submission of the online quizzes will not be accepted as the answers will be discussed at the following lecture.

    The written assignments are provided as part of the learning experience. Students are expected to enhance their knowledge and understanding of the subject matter through completing the assignments. The assignments are marked and the results included in the final assessment to ensure that students actually do the assignments and take them seriously. Solutions to the assignments are discussed in class.

    The FEA project provides students with the opportunity to demonstrate their comprehension of the course material. The project is marked and included in the final assessment so that students take it seriously.

    Assignments and the project are also used to help assess whether the required graduate attributes are being developed.

    The examination is a summative assessment and is intended to assess the student’s knowledge and understanding of the course material and how it fits into the global engineering context. The final examination is open-book.

    The Late Penalty for assignments and the FEA Project is 10% per each end of day. Hence weekends lose 3 days = 30%.

    Submission

    The online quizzes will be submitted through MyUni (MapleTA).

    Written assignments are to be submitted to the appropriate submissions box located on level 2 of Engineering South Building with a standard plagiarism coversheet completed and attached to the assignment.

    Late submission of the online quizzes will not be accepted as the answers will be discussed at the following lecture the next day.

    The Late Penalty for assignments and the FEA Project is 10% per each end of day. Hence weekends lose 3 days = 30%.

  • Student Feedback

    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.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    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.
