Structures and Mechanical Properties of Engineering Materials - Coursework

Coursework Objectives

• The course work aims to address all the module learning outcomes by focussing on the quantitative descriptions on Structures and Mechanical Properties of Engineering Materials and by incorporating a comprehensive understanding of the various failure modes and design criteria for materials selection.

• The module learning outcomes are provided in the coursework brief.

• University requests all student to use a uniform coursework cover sheet for submission. Please use the assessment cover sheet provide in the Blackboard to submit the coursework as a single document.

• Please look into the coursework brief for the questions .

• The entire coursework is based on the taught lectures and tutorial sessions for the module. Read through the lecture materials, exercise and tutorial problems and supplementary materials provided in the Module Material area in the Blackboard space for the module.

Please note that this is the final time you can submit – not the time to submit!

Question with Answers to the Course Work will be uploaded in the Blackboard after the submission deadline. Detailed discussion of the solutions to the Course Work will be discussed in the class during the revision lecture session for the module.

1. The coursework should be your own work and should be properly type-written in your own words. Your assignment must be submitted electronically via blackboard by the submission time or before.

2. Please see the instructions to candidates for more information (Page Number - 4).

• Any questions arising from this assessment brief will be discussed in the class, online forum during the lectures/tutorial session. Please contact Dr. Arun Natarajan (Module Leader/Module Tutor) if you have any further queries. E-mail: [email protected]

• For support with using library resources, please contact Mr Bob Frost, E-mail: [email protected] or [email protected]. You will find links to lots of useful resources in the My Library tab on Blackboard.

• If you have not yet made the university aware of any disability, specific learning difficulty, long-term health or mental health condition, please complete a Disclosure Form. The Inclusive Support team will then contact to discuss reasonable adjustments and support relating to any disability. For more information, visit the Inclusive Support site.

• If you have any other query or require further support you can contact The <i>, The Student Information and Support Centre. Speak with us for advice on accessing all the University services as well as the Library services. Whatever your query, our expert staff will be able to help and support you. For more information , how to contact us and our opening hours visit Student Information and Support Centre.

• If you have any valid mitigating circumstances that mean you cannot meet an assessment submission deadline and you wish to request an extension, you will need to apply online prior to the deadline.

Cylindrical shaped pressure vessel with both ends opened

(a) Translation of problem indicating function, objective, constraints and free variables?

(b) Derive the performance material index for failure.

(c) Discuss the implication of two performance index i.e., due to yielding and fast fracture for the selection of one material. Find the coupling line by making equal the cost calculated with the two indexes.

(d) Use CES EDUPack  to create a graph representing the material index and identify the region of the chart with the cheapest materials for the pressure vessel due to yielding and fast fracture material index.

Use the concept of coupling line for selecting best material materials for the cylindrical pressure vessel due to yielding and fast fracture material index.

(ii) Spherical shaped pressure vessel

(e) Translation of problem indicating function, objective, constraints and free variables?

(f) Derive the performance material index for failure.

(g) Use CES Edupack (Rebranded as GRANTA EDUPACK 2020) to create a graph representing the material index and identify the region of the chart with the cheapest materials for the for the pressure vessel due to fast fracture material index.
