MATERIALS SELECTION AND DESIGN

The verification of the expected knowledge is carried out through a written test and a "practical" test.

The written exam consists of 9 questions, on the whole program of the course. The 9 questions consist of open-ended questions and exercises, with answer placed within predetermined spaces, as follows:
1. short question, requiring an answer in a maximum of 3-4 lines; it is a matter of remembering the principles of the selection of materials through indices and graphs, for a maximum of 2 points
2. extended question, requiring a structured, but synthetic (10-12 lines) answer, also with the support of schemes; the question concerns one of the fundamental case studies regarding the selection of materials through indices and graphs; the complete mastery of the characterizing equations and of the mathematical treatments is required in order to obtain suitable indices. The answer yields a maximum of 5 points; the student can choose to answer an alternative question, similar but simpler, for a maximum of 3 points
3-4-5. short exercises of graphic selection and / or numerical selection with multiple objectives, each for a maximum of 3 points; a full understanding of the graphical and numerical algorithms, coupled with precision in the calculations, is required
6. short exercise of selection of materials and shape, for a maximum of 3 points; a full understanding of the graphical and numerical algorithms, coupled with precision in the calculations, is required
7. extended question, requiring a structured, but synthetic answer (as above); it is a matter of remembering the principles of the design of composite materials for advanced applications (reporting constitutive equations and / or architectures), for a maximum of 4 points
8. short exercise of graphical evaluation of the efficiency of composites: it is a matter of discussing, by means of graphs, the efficiency of composites for fundamental applications, with the support of selection indexes, for a maximum of 3 points.
