Learning Outcomes
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. 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 Have an understanding of the selection, design and stress analysis of composite materials. 7 Possess the ability to analysis the stresses in simple structures as used in the aerospace industry. 8 Further develop interpersonal understanding, teamwork and communication skills working on group assignments. 9 Be able to learn independently new solutions, principles and methods, read and understand professional articles on the subject.

Assessment
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.
Assessment Summary
The Solid Mechanics module is worth 50% of the total course assessment and the Materials & Structures module worth 50% of the total course assessment
The Final exam will be scheduled in week 15 or 16. Half of the exam will be for the Solid Mechanics module and half will be for the Materials & Structures module.
The following tables are an outline of the assessment for each module of this course. Please note that while every effort has been made to ensure that this information reflects an accurate plan, the coordinator and lecturers have 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.

All other assignments and reports must be submitted as a hard copy (unless stated otherwise) accompanied by an assessment cover sheet available near the assignment submission area. These must be placed the labelled box 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.

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.

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鈥檚 disciplinary procedures.
