THE AIMS OF THIS MODULE ARE:
• To underpin and extend the theoretical concepts and design criteria related to three dimensional stress analysis of automobile structural components, sub-assemblies and assemblies.
• To extend the students’ knowledge in vehicle engineering and to provide confidence in the application of mechanics of mechanics of materials’ theories to real structural problems.
• To provide the base for using typical examples found in industry.

Performance in unseen examinations are likely to form a major part of the evidence of attainment for the outcomes. Evidence from laboratory based assignments that are designed to apply the theoretical concepts will also be collated. All learning outcomes will be assessed by one or more of the following:
• Unseen time constrained test environment using conventional examination[s]; and
• Laboratory based assignments and/or case study investigations forming the coursework element.
Examinations will be used to illustrate the learners’ ability in an individual time constrained environment whilst, case study and/or laboratory based assignments will provide evidence of the extent of learners’ understanding and applications of principles.
when you have successfully completed this module you will:
to demonstrate that you have achieved the learning outcome you will:
|1.||Apply appropriate engineering science methods in verifying both software and experimental results.
Correctly analytically calculate 3D stress/strain values and compare these with that obtained through the use of software/experiment.
|2.||Carry out appropriate experimental and theoretical techniques to assess the suitability of automobile structural body components and sub-assemblies in relation to failure and damage.
Correctly evaluate the difference between closed form and approximate solution and reflection on how the difference ad its effect can be minimised.
|3.||Employ industry standards in the design of vehicle body structures.
Use industry computer packages, European and American standards on vehicle safety in the design of new vehicle body structures.
|4.||Judge the structural problem posed and generate a sequence of steps necessary to solve the problem
Select the appropriate techniques and justify the achieved solution.
|5.||Model structural components, sub-assemblies and assemblies in order to simplify otherwise complex problems into say shear panel methods.
Appraise a problem by developing an appropriate model.
|6.||Solve complex structural problems using a number of methods that provide good approximations to the experimental results.
Use appropriate computer software in modelling structural components, sub-assemblies and complete vehicles.
|7.||Competently carry out experimental work on vehicle structures including both analytical and numerical analyses.
Correctly interpret the experimental, analytical and numerical results, and present them in a report form to be discussed and scrutinised by peers.
|8.||Model vehicle structures using industrial tools, thereby prepare the student for the work in the automotive industry.
Correctly apply advanced functions that are suitable in evaluating complex problems.
