Prerequisites: The course includes basic knowledge of General Chemistry, Metallic Materials and Mechanics of Solids
Target skills and knowledge: The Course in its various parts is expected to provide the following knowledge and skills:
1. To be able to recognize the correlations between microstructure and properties of non-metallic materials, ie ceramic materials (including glasses), polymers and composites (including cement and concrete)
2. To be able to interpret and control the brittle fracture of mechanical components
3. To be able to recognize the fundamental aspects in the design with non-metallic materials (eg control of the effect of size and time on the mechanical strength of ceramics, control of the effect of temperature on the mechanical properties of polymers, control of the mechanical properties of composites mechanics by means of specific architectures of the reinforcing phase)
4. To be able to separate and enhance the contribution of materials from the contribution of geometry and operational constraints in the performance of industrial components
5. To be able to recognize the decisive combinations of properties in the selection of materials for mechanical engineering applications
6. To be able to apply graphical and / or numerical algorithms for a quick selection of the most suitable materials for the manufacturing of mechanical components
Examination methods: The expected learning is verified by means of a written test. The test consists of 9 questions, on the whole program of the course. The 9 questions in turn consist of open-ended questions and exercises; the answers must stay within predetermined spaces, as follows:
- 5 questions and short exercises, which require an answer in a maximum of 3-4 lines; it is a matter of remembering fundamental definitions and descriptions, for which the precision and the ability to synthesize are greatly appreciated. Each short question corresponds to 2 points; one of the 5 questions contains an additional, optional request for a further point; the maximum score obtainable from the 5 short questions is therefore 10-11 points
- 3 exercises: this section involves the application of design criteria for ceramic materials and composites and / or numerical algorithms and graphs of materials selection, for specific applications, from the analysis of properties; the precision in the calculations and the accuracy in the application of the selection algorithms are appreciated. Each exercise corresponds to 3 points; the maximum score obtainable from the three exercises is therefore 9 points
- 1 extended question, for a maximum of 12 points, which requires a structured (but, in any case, concise) answer, at most on two A4 facades; it refers to one of the numerous case studies concerning the engineering application of ceramic and composite materials and / or the selection of materials through the analysis of significant properties and their combination.
The sum of the scores from short questions, exercises and extended question determines the final grade. The maximum grade ("30/30 cum laude") is awarded for a final score of at least 31.5 points.
The written test can be replaced by two review tests, i.e. midterm review test and final review tests (the second test is carried out in correspondence with the first call). The first test is in "quiz mode", i.e. on 21 multiple choice questions (4 options, 1 valid only), on topics of the first part of the course (excluding composites); each question corresponds to 1.5 points (maximum = 31.5). The answer presupposes the full mastery of definitions and descriptions, or mathematical treatments. The second test consists of a written test with the same organization as the written exam test, but with questions and exercises related to the second part of the course only. The final grade is expressed as the average of the scores in the two review tests.
Assessment criteria: The evaluation criteria consist of:
1. Completeness of the acquired knowledge
2. Property of technical terminology
3. Accuracy in the application of design criteria for ceramic and composite materials
4. Consistency and precision in the application of numerical and graphical algorithms for material selection
Course unit contents: Structure of ceramic materials: ionic and covalent crystals, binary and ternary structures, structure of silica and silicates, glasses. Defects in ceramic materials. Mechanical properties of ceramics: elastic behaviour, fracture mechanics, toughening mechanisms, fatigue, creep, mechanical testing, lifetime predictions of a ceramic component. Thermal properties of ceramics.
Structure of polymeric materials: polymeric molecules, molecular structure and shape, polimerization processes. Mechanical and thermo-mechanical properties of polymers: stress-strain behaviour, factors affecting the mechanical properties of polymers, fracture of polymers. Main manufacturing processes of polymers. Composite materials: particle reinforced composites, fibre reinforced composites. Mechanical properties of composite materials. Cements and concretes: types, structure and mechanical properties of cementitious materials.
Identification of materials indexes. Selection as a function of multiple objective and constraints. Selection of materials and shapes. Design of components with complex combinations of properties
Planned learning activities and teaching methods: The teaching activities include classroom hours during which, on computer support (projected slides), the course contents are progressively presented. Demonstrations and examples of calculation are developed step by step on the blackboard.
Additional notes about suggested reading: The teaching material presented during the lessons (constituting the topics of the exam) consists of:
- reference textbook (part of 'non metallic materials', in italian)
- free textbook on materials selection (available in the Moodle platform)
- slides (the same ones projected during the lessons, available in the Moodle platform)
Each lesson corresponds to a single chapter of and a single block of slides.
Various examples of exercise, including solutions, are available.
