Learning Outcomes
Course Learning Outcomes
The aim of this course is to develop an understanding of the mechanics of fracture of engineering materials and structures under static and dynamic loading. This understanding is essential for the assessment of integrity and durability of structures and structural components in the presence of structural defects, so as to ensure reliability and safety. At the completion of the course, students will:
1 Have a solid foundation in the theory, concepts and principles of fracture mechanics, 2 Be gaining the physical intuition necessary to idealise a complicated practical problem, 3 Possess the analytical and computational tools needed to solve the idealised problem, 4 Have acquired the 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 and, 6 Be able to work independently and as part of a team in order to implement their skills and knowledge in both theoretical and practical applications.

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.

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.
The 成人大片 is committed to regular reviews of the courses and programs it offers to students. The 成人大片 therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
