The module descriptors for our undergraduate courses can be found below:
- Four year Aeronautical Engineering degree (H401)
- Four year Aeronautical Engineering with a Year Abroad stream (H410)
Students on our H420 programme follow the same programme as the H401 spending fourth year in industry.
The descriptors for all programmes are the same (including H411).
This module introduces the fundamental concepts for all structural analysis, viz equilibrium, compatibility and the stress/strain law. It illustrates the use of these concepts to solve simple problems, mainly concerning frameworks and beams, and to apply them in tutorials and laboratory practicals.
On successfully completing this module, you should be able to:
1. define stress and strain and the symbols and conventions in 3-D, introduce the material properties and show their relationship to stress and strain via constitutive laws.
2. demonstrate understanding of the small displacement hypothesis for pin-jointed frameworks, find all the forces in a pin-jointed framework using joint equilibrium and apply the principles of superposition and symmetry. Use this to identify a pin-jointed framework as being: statically determinate, redundant or a mechanism.
3. express the strain in any bar in terms of its end displacement components and construct the deflected shape of a framework if the bar forces are known.
4. solve for the deflection in a statically-determinate framework using the virtual work method and in terms of the joint.
5. derive the governing equations for slender beams using the same principles of compatibility, equilibrium and the stress/strain law, construct the shear force and bending moment diagrams for a variety of beam problems and solve for beam deformations by direct integration and by the virtual work method.
6. identify statically-indeterminate beams and solve for single redundancies using the principles and methods learned earlier.
7. derive the equations for a circular section beam loaded in torsion and to show that these are similar to the equations for beam bending and solve some examples for displacement and shear stresses.
8. derive the equations for the analysis of thin-walled beams with non-symmetric sections and solve for bending stresses and deflections.
Introduction: structural analysis as part of the design process.
Stress/Strain: definition and convention for all stress components in 3-D. Definitions of: strain, including thermal strain; constitutive (stress/strain) law; Young’s modulus; shear modulus; Poisson’s ratio.
Pin-jointed frameworks: statically determinate: forces and displacements. The virtual work method.
Redundant frameworks: solution in terms of joint displacements.
Engineer’s Theory of Beams: assumptions, strain/curvature and stress/moment relationships.
Shear force and bending moment diagrams.
Direct solution of deflections from curvature.
Displacement by the virtual work method.
Torsion of circular section beams.
Thin-walled beams with non-symmetric sections and the concept of principal axes.
The module will be delivered primarily through large-class lectures introducing the key concepts and methods, supported by a variety of delivery methods combining the traditional and the technological. The content is presented via a combination of slides, whiteboard and visualiser.
Learning will be reinforced through tutorial question sheets and laboratory exercises, featuring analytical, computational and experimental tasks representative of those carried out by practising engineers.
This module presents opportunities for both formative and summative assessment.
You will be formatively assessed through progress tests and tutorial sessions.
You will have additional opportunities to self-assess your learning via tutorial problem sheets.
You will be summatively assessed by a written examination at the end of the module as well as through practical laboratory assessments and a written laboratory report.
|Assessment type||Assessment description||Weighting||Pass mark|
You will receive feedback both during the laboratory sessions and following the coursework submission.
You will receive feedback on examinations in the form of an examination feedback report on the performance of the entire cohort.
You will receive feedback on your performance whilst undertaking tutorial exercises, during which you will also receive instruction on the correct solution to tutorial problems.
Further individual feedback will be available to you on request via this module’s online feedback forum, through staff office hours and discussions with tutors.
