Module Title:Aircraft Structures
Language of Instruction:English
Credits: 10
NFQ Level:8
Module Delivered In 1 programme(s)
Teaching & Learning Strategies: The module will be delivered using lectures, tutorials and laboratory sessions to illustrate the concepts under study
Module Aim: To provide the student with: *The skills to analyse the internal effects of forces applied to the members in structures of complex or asymmetric section, as evidenced by the stresses and deformations resulting. *The skills to apply specialised techniques, such as CAD/FEA/CFD, to analyse the behaviour of structural members under load in mechanical and aerospace structural applications.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Carry out analysis of the deformation of asymmetric members (such as found in aircraft structures) under load by analytical means. Use specialized analytical techniques such as Mohr’s Circle to produce detailed analyses of structural materials under load. Use the relevant theories of failure as a tool in the design of load-bearing structures
LO2 Understand the mathematical and physical principles underlying the Finite Element Method (FEM) as applied to solid mechanics, thermal analysis and fluid mechanics
LO3 Be able to analyse complex problems (in solid mechanics or thermal analysis) using commercial FEM software packages. Demonstrate the ability to design a component using FEM analysis
LO4 Understand the importance of analysis and design, using the FEM, in the broader context of engineering practice
LO5 Contribute effectively, as an individual and as part of a group, to the planning and realization of investigations in a laboratory environment into the behaviour of structural materials in service. Make clear and effective technical presentations, in terms of form and content, of his/her work
