Synopsis

Finite element analysis (FEA) in computer-aided design; finite element formulation; first-order and second-order elements; stiffness matrix; integration points and stress recovery; convergence and mesh refinement; FEA of plane stress and plane strain problems; FEA of axisymmetric problems; FEA of nonlinear materials; FEA of contact problems; FEA of large deformation problems; FEA of dynamic problems; FEA of fracture mechanics.

Outcomes

At the successful completion of this unit you will be able to:

  1. Identify 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. Select correct element types and designs proper mesh to obtain accurate results from a finite element analysis.
  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. Identify the basic theories and concepts of advanced solid mechanics, such as nonlinear materials, contact mechanics, finite deformation and fracture mechanics.
  6. Use finite element analyses on advanced solid mechanics problems.

Assessment

Continuous assessment: 60%

Examination (2 hours): 40%

Students are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

Workload requirements

2 hours of lectures, 2 hours of laboratory/tutorial classes and 8 hours of private study per week.
