Target skills and knowledge: The course provides the basis for a comparative choice of materials in relation to the function of the component, the objectives of the selection and the choice constraints. At the end of the course the student will have acquired the ability to select the material starting from the entire family of materials available on the market through a fast and systematic method that is well suited to all phases of mechanical and industrial design, a fundamental requirement for product innovation. In selecting the material, neither the choices related to the production process, nor the problems related to the environmental impact (eco-design) are neglected. Finally, the student will acquire the ability to solve 'open-ended design problems' through compromise strategies.
Examination methods: The verification strategy includes a practical test and an oral exam. In the practical test the student will choice a mechanical component and will apply the systematic materials selection strategy by proposing innovative solutions. The project will be delivered towards the end of the course, and the procedure and the proposed solutions will be exposed during a frontal lesson as a subject for further study and discussion. The paper and its presentation will be evaluated ant the corresponding grade will average with the final grade obtained at the end of the oral verification.
For the practical project, students will be able to access to the 'Cambridge Engineering Selector' database of GRANTA design, which will be opportunely introduced also during the lectures.
In the oral examination, theoretical questions related to the course contents will be preferred.
It is believed that this modality of examination can represent a valid methodology able to make the course contents more familiar and practical, encouraging the student's ability to select new materials.
Assessment criteria: The evaluation of the student preparation will be based on his understanding of the arguments, on the acquisition of the concepts and methodologies proposed as well as on the ability to apply them in an autonomous and conscious way.
The student must demonstrate to be able to face an 'open-solution design problem' by critically analyzing the design requirements and constraints.
Course unit contents: The course contents can be summarized as follows:
1. The mechanical design. The design process. Design tools and data on materials.
2. The families of engineering materials. Materials properties.
3. Types of materials data: numerical and non-numerical data. Data organization on materials: structured and unstructured data. Diagrams of properties. Tabulated data and diagrams for individual properties. Diagramed data for combinations of properties.
4. Selection strategy in relation to the functionality of the component, the objectives of the selection, the choice constraints. Limit attributes and material indices. Performance maximization criteria trough combined property diagrams and guidelines.
5. Materials selection: case-studies
6. Process selection. Classification of processes. Process families.
7. Process selection: case-studies
8. Selection under multiple constraints. Contrasting objectives, penalty function and exchange constant (open-ended design problem solving)
9. Multiple constraints and conflicting objectives: case-studies
10. Choice of material and shape. Shape factors. Limits to the shape efficiency. The structural sections. Indexes of materials that include the shape
11. Choice of material and shape: case-studies
12. The design of hybrid materials. Bridging the gaps in the M-P space. The method 'A + B + configuration + scale. Hybrids, types 1, 2, 3, 4
13. The design of hybrid materials: case-studies
14. Eco-design. The life cycle of materials. Use of materials and energy. Ecological characteristics of the materials. Eco-selection.
15. Selection of materials for mechanical components in relation to issues related to critical raw materials
Planned learning activities and teaching methods: The learning activity includes lectures and a practical section held by the student in parallel to the course. The lectures are alternated with a theoretical part, in which the principles of the method are explained, and one of in-depth study through the analysis of case-studies useful for the student to become familiar with the selection method and the possible problems connected to it. The practical part carried out by the student, is object, at the end of the course, of further study through its exposure to colleagues in the classroom. The course involves the use of slides that are projected during the lesson and previously provided to the students. The PowerPoint presentations also contain video material useful for improving the learning and before each new topic exposition the concepts related to the previous lesson are briefly summarized to facilitate the students to link the different contents of the course. The materials selection strategy involves the use of the 'Cambridge Engineering Selector' (CES) program by Granta Design which is made available to students already at the beginning of the course to allow them to become familiar with it. This program is also used for educational purposes thanks to the various educational tools it contains.
Additional notes about suggested reading: The materials for study are:
1. copy of the slides projected during the frontal lessons which students are invited to take notes on
2. Cambridge engineering selector software, where the student can find a lot of information related to the material selection strategy

Both handouts and software are provided at the beginning of the course
