MATERIALS SELECTION IN MECHANICAL DESIGN - 2020/1
Module code: ENG3206
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
A lecture and tutorial based module, which build on ENG1063 (Materials and Statics), and is complementary to ENG3164 (Engineering Materials). It provide a deeper and broader appreciation of methods for selecting materials as part of mechanical design.
Materials property charts are used throughout as a means to rapid appropriation of solutions from a wide range of engineering materials. The module includes the selection of materials processes in addition to selection of materials. Approaches that enable multiple constraints and conflicting objectives to be handled are explored. Materials selection and component shape is addressed as a pointer to more sophisticated contemporary approaches such as topological optimisation. The module concludes with an overview of designing hybrid materials.

- Indicative content: The basics of materials selection: the selection strategy, attributes and materials indices, the selection procedure. Case studies, including couplings, seals, safe pressure vessels and heat exchangers. [9L, 3T]
- Processes and their effect on properties. Shaping, joining, finishing. Subtractive and additive manufacture. Process-property trajectories. Process selection. Limitations and quality. [6L, 2T]
- Multiple constraints and conflicting objectives: Selection methods for multiple constraints. Case studies: light pressure vessels, wafer-thin casings for hand-held technology, cost-effective bumpers and materials for disc-brake callipers. [6L, 2T]
- Selection of materials and shape: a refresher on shape factors. The limits to shape efficiency. Material indices that include shape. Architectured materials: microscopic shape. Case studies, including forks for racing bicycles, shapes that flex and ultra-efficient springs. [6L, 2T]
- Designing hybrid materials: cellular structures (foams and lattices). Sandwich structures and multilayers. Segmented structures. Case studies, including: designing metal matrix composites and exploring the efficiency of natural materials. [3L, 1T]
- Review. [2L]

There is no alternative assessment (a late summer assessment will follow the same assessment pattern as that followed during the running of the module in semester time).
The assessment strategy is designed to provide students with the opportunity to demonstrate:
(i) they understand how to use diverse engineering materials property data to select appropriate materials for structural applications in a variety of engineering contexts,
(ii) can use engineering materials property data to justify the selection of materials, processes and component geometry against various design goals.
Thus, the summative assessment for this module consists of:
· Assignment [learning outcomes 1 and 2]; 15 hours; (20%).
· Examination [learning outcomes 1, 2, 3 and 4]; 2 hours (80%).
Formative verbal feedback is given in tutorials.
Written feedback is given on the coursework assignment.
- To understand how to use diverse engineering materials property data to select appropriate materials for structural applications in a variety of engineering contexts.
- To use engineering materials property data to justify the selection of materials, processes and component geometry against various design goals.

Methods of Teaching / Learning
The learning and teaching strategy is designed to enable students to:
(i) use materials property charts to make initial judgements about the selection of materials for diverse engineering design contexts, (ii) understand a broad range of processes for materials manufacture and their implications for materials and process selection, (iii) analyse the mechanics of a materials design problem so as to select materials and geometry to minimise weight, minimise environmental impact, etc., (iv) assess when a hybrid material might provide a better design solution than a monolithic engineering material.
The learning and teaching methods include:
33 hours of lectures over 11 weeks
10 hours of tutorials over 10 weeks
15 hours of assignment work.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
