Assessment

The Handbook lists an examination for this unit.

Continuous assessment: 60% Final assessment: 40% This unit contains hurdle requirements that you must achieve to be able to pass the unit. You are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final assessment component. The consequence of not achieving a hurdle requirement is a fail grade (NH) and a maximum mark of 45 for the unit

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.

Requisites

Learning outcomes

1. Apply the basic theories, terminologies and concepts related to the application of the finite element method in computer-aided design of structures, including aircraft structures.
2. Justify the selected correct element types and mesh density in a finite element model for obtaining accurate results.
3. Generate finite element models for truss structures, plane stress, plane strain, axisymmetric and general 3D structural problems.
4. Apply a commonly-used commercial software to carry out finite element analyses on different structural problems.
5. Interpret the basic theories and concepts of advanced solid mechanics, such as nonlinear materials, contact mechanics, finite deformation and fracture mechanics.
6. Apply the finite element method in solving advanced solid mechanics problems.

Workload

The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-6 hours of scheduled learning activities and 6-9 hours of independent study per week. Scheduled activities may include a combination of teacher-directed learning, peer-directed learning and online engagement. Independent study may include associated readings, assessment and preparation for scheduled activities.

Student experience, not official rules. Nothing here changes what the Handbook says.
