MMA4001 · Finite element analysis

Overview

In this unit, you will be introduced to finite element analysis (FEA) in computer-aided design, including the formulation of finite elements. You will study first-order and second-order elements, the stiffness matrix, integration points, and stress recovery, as well as concepts of convergence and mesh refinement. You will then apply FEA techniques to plane stress and plane strain problems, axisymmetric problems, nonlinear materials, contact problems, large deformations, dynamic problems, and fracture mechanics.

Requisites

Learning outcomes

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.

Workload

The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-5 hours of scheduled learning activities and 7-9 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.
