NFQ Level:8
Module Delivered In 1 programme(s)
Teaching & Learning Strategies: The module will be delivered using lectures, tutorials and laboratory sessions.
Module Aim: To provide the students with the knowledge and skills required for evaluate a range of structures under complex loading condition by analytical and numerical analysis.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Analyse complex stresses and strains due to combined loading and loading on oblique plains.
LO2 Plot the stresses and strains at any plane across the field using graphical methods such as Mohr’s circle.
LO3 Apply the theories of elastic failures to composite structures and assymmetric beams.
LO4 Execute the mathematical and physical principles underlying linear static structural Finite Element Analysis (FEA).
LO5 Analyse complex structural problems using commercial FEA software packages. Demonstrate the ability to design a component/assembly and carry out bolted joint analysis using FEA
LO6 Contribute effectively, as an individual or as part of a group, to the planning and realization of investigations in a laboratory environment into the behaviour of structural materials in service.
