Course Learning Outcomes
The primary aim of the course is to provide students with the basic skills and knowledge required to analyse displacement field, stress, strain and failure in deformable solids using analytical solutions and the Finite Element Method. The course develops an understanding of the mechanics of complex practical situations through the establishment and solution of appropriate boundary value problems. It will also give students an overview of important structural engineering design philosophies. The course forms a foundation to allow more effective interactions with civil and structural engineers during their professional careers. Students will carry out design tasks, supported by quality assurance and verification strategies associated with risk management as used in industry.
At the completion of the course, students should:
1 Have a good understanding the theory, concepts, principles and governing equations of solid mechanics; 2 Be gaining the physical intuition necessary to idealize a complicated practical problem; 3 Possess the contemporary analytical, experimental and computational tools needed to solve the idealized problem; 4 Have acquired the independent judgment required to interpret the results of these solutions; 5 Be able to use these solutions to guide a corresponding design, manufacture, or failure analysis; 6 Further develop interpersonal understanding, teamwork and communication skills working on group assignments; 7 Be able to learn independently new solutions, principles and methods, read and understand professional articles on the subject.

Specific Course Requirements
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
The Final exam will be scheduled in week 15 or 16.
Solid Mechanics Part worth 50% of the course assessment
All assignments are due by 5pm on the due date. Details of each task are tabulated below.
Assessment task Weighting, % Description Due Learning objectives

Structural Design Part worth 50% of the course assessment
All assessment tasks (except the final exam) require groupwork, the same mark will be allocated to all group members and will be based on group output only. Group processes are not assessed explicitly in this course. All members in a group are expected to contribute equally to the overall task. In cases of unequal contributions to groupwork, students should complete a self-and-peer assessment form.
Assessment task Weighting, % Description Due Learning objectives

Solid Mechanics part
Assignments 1 - 3
There are problem-solving exercises. These problems will be discussed in class in detail before the due date. Example problems with full worked solutions will be considered in class and the solutions of the assignment’s problem will be available on MyUni.
FE Tutorials Report
This is an individually written assignment on the FE modelling part of the course and will involve problem-solving exercises. The timetable for FE tutorials will be available on MyUni in the beginning of semester.
Lab Classes Report
This is a group assignment on the experimental study part of the course. The timetable for the lab classes will be available on MyUni in the beginning of semester.
Quizzes are individual in-class assignments and this includes problem-solving exercises to be completed in normally 45 min with full worked solutions to be available on MyUni.
Structural Design part
All assessment tasks (except the final exam) require groupwork. The objective is to provide students with the experience of working in groups to undertake open-ended design tasks. These types of problems reflect the challenges presented to engineers in industry, whereby efficient designs must be supported by rigorous quality assurance strategies in order to mitigate risk. The truss design involves conceptual, preliminary and final design procedures. This is supported by the preparation of engineering calculations and drawings, along with the construction and testing of a model truss to determine the robustness of the design. The aim is to minimise the strength-to-weight ratio of the structure to maximise efficiency. The reinforced concrete design involves design calculations and an investigation into the multi-disciplinary aspects of the design and construction of a real-life building. All aspects of the course include quality assurance strategies including self and peer-checking, and verification.
Solid Mechanics part
Quiz will be collected at the end of tutorial.
All other assignments must be submitted as a hard copy accompanied by an assessment cover sheet available from S116 or near the assignment submission area. These must be placed the labelled box located on level 2 of Engineering South Building.
Late assignments will be penalised 10% per day. Extensions for assignments and reports will only be given in exceptional circumstances and a case for this with supporting documentation can be made in writing after a lecture or via email. Hard copy assignments will be assessed and returned in 2 weeks of the due date. There will be no opportunities for re-submission of work of unacceptable standard.
Structural Design part
Assessment tasks (except the final exam) must be submitted as a hard copy accompanied by a signed assessment cover sheet. These must be placed in the labelled mail box adjacent to room N136, Engineering North (i.e. front office of the School of Civil, Environmental and Mining Engineering).

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.

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.
