Aerospace engineering

1. Introduction to Materials Science and Technology 2. Atomic structure and interatomic bonding (atomic structure, interatomic bonds in solids, the structure of crystalline solids, non-crystalline solids, point, linear and bulk imperfections in solids) 3. Diffusion (Fick’s first and second law) 4. Mechanical properties of metals (elastic deformation, plastic deformation, property variability and design/safety factors) 5. Dislocations and strengthening mechanisms (dislocations and plastic deformation, mechanisms of strengthening in metals, recovery, recrystallization and grain growth) 6. Failure (ductile and brittle failure, fatigue, creep) 7. Metallic materials (definitions and basic concepts of binary phase diagrams, types of metal alloys, fabrication of metals) 8. Ceramic materials (ceramic structures, mechanical properties, types and applications of ceramics, fabrication and processing of ceramics) 9. Polymers (mechanical behaviour of polymers, mechanisms of deformation and for strengthening of polymers, crystallization, melting and glass transition phenomena in polymers, polymer types, polymer synthesis and processing) 10. Composites (particle-reinforced composites, fibre-reinforced composites, structural composites, natural fibre reinforced composites)

The materials field represents an interdisciplinary subject, spanning the physics and chemistry of matter, engineering applications and industrial manufacturing processes. Therefore, the students are expected to have a good knowledge of maths and fundamental sciences including chemistry, physics and mechanics of materials.

The teaching activities are organized in traditional lecture-based classes for the acquisition of knowledge. Students will be actively engaged by collecting information and asking questions. Numerical exercises will be solved in class in order to make theory more easily learned.

Class attendance is not compulsory, even though it is highly recommended.

The assessment will be based on the results of a written test and oral interview, aimed at verifying the acquisition of the following knowledge and skills: - knowledge of microstructure, properties, design, production and transformation processes, use, analysis, characterization, degradation and recycle of materials of interest for industrial engineering; - ability to apply this knowledge to select the materials suitable for different applications, to recognize the conditions of potential in- service risks, to choose the most appropriate tests to evaluate the performance of materials. The written test will last 90 minutes and will include five multiple choice questions on the topics discussed in class, and three numerical exercises, which are designed to develop students’ understanding of concepts and facility with skills. The final mark resulting from the written test is based on the quality and thoroughness of the answers and related reasoning. It is required a minimum grade of 18/30 to access the oral interview. The minimum grade for passing the exam (18/30) is achieved only if the student is able to correctly classify and discuss the physical-mechanical properties of the main classes of materials of interest for industrial engineering. For the final evaluation the following aspects will be considered: - the level of knowledge - the ability to securely correlate different topics - the ability of applying knowledge to the solution of problems of limited complexity in the field of materials engineering - the ability to communicate the acquired knowledge and to illustrate the technical solutions proposed with clarity using a proper technical vocabulary. In order to obtain the highest mark (30/30 cum laude), the student must demonstrate that he/she has acquired excellent knowledge of all the topics covered in the course, and that he/she can apply this knowledge to the solution of problems in the field of industrial engineering, proposing original solutions and showing the results of an autonomous extension of knowledge.
