  • Learning & Teaching Activities
    Learning & Teaching Modes

    The course material is delivered through weekly lectures and demonstration tutorials. The lectures cover various topics of stress analysis and design, with a focus on the practical applications of stress analysis to real world problems. The demonstration tutorials focus on the development of problem solving and communication skills in the context of the design of simple structural components widely utilised across engineering designs.


    The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

    The workload for the course comprises of lectures, demonstration tutorials and practical components. The assessments include 10 online quizzes, 3 in-class tests, 3 home assignments, 2 individual practical reports, and the final examination.

    The 10 weekly online quizzes consist of simple problems aimed to enhance the understanding of basic concepts and methods presented during the weekly lecture and tutorial.

    The 3 in-class tests are conducted to develop time-managment and problem solving skills. They will consist of 3-4 more in-depth (exam style) problems. The purpose of these tests is to prepare students for the final exam.

    The 3 home assignments includer problems which are more advanced than the problems discussed in lectures and tutorials. The assignment problems are aimed at challenging the students intellectually and providing stimulus for students to extend their conceptual understanding in a self-directed manner.

    The 2 practical components of this course are the DIC / Beam bending laboratory and the FEA computer exercises. During the DIC / Beam bending laboratory students will be introducted to contempary experimental methods for the analysis of strains (strain gauge technique and digital image correlation). The FEA classes introduce computational-based methods which are the main tool for design and stress analysis in industry. Both components will be assessed by an individual report. Each practical is a hurdle assement in which the student must score above 50% to pass the course.

    The final examination is intended to assess the student’s overall knowledge and understanding of all topics covered in the course. The final examination is a hurdle assessment in which the student must score at least 40% to pass the course.

  • 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.

  • 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 ( 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.
