The aim of the course is to provide the student with fundamental knowledge of Materials Science and Materials Engineering, for the purposes of Mechanical Engineering, dealing in detail with the study of structure-property correlations in order to define the product-process most suitable for a defined use. The students will be provided with knowledge on the properties of all classes of materials (metals, ceramics, polymers and composites), on the methods for their determination, on how to get a functionalization for specific applications and on the technological production process.

Provided knowledge: cc3-Systematic knowledge and understanding of the key aspects of mechanical design of industrial engineering and its methods. In particular: understanding of which are the most suitable methods in order to define a product and its characteristics; knowledge of the technology of the materials that can be used, of the mechanical study of parts and assemblies, their dimensioning, their static and dynamic behaviour and interactions between components. The technologies for their production and their graphic representation are also areas of knowledge and understanding.
Application ability: ca3-Applying knowledge and understanding related to the most appropriate methods of analysis, modelling, verification and experimentation to design, analyze and test machines and plants. This includes: the interpretation and drafting of mechanical parts and machines (also using dedicated CAD systems); the sizing and the functional and structural verification of components and mechanical groups subjected to static and fatigue stress; the functional setting of the design of a mechanical system, applying the principles of kinematics and static principles; analysis of the characteristics of metallic and polymeric materials for the production; the choice of the best production process aimed at the creation of mechanical components; analysis and design of production systems including the study of reliability, safety and economic and environmental sustainability.

Physics, Chemistry and Technology of Materials and Applied Chemistry.

The course is held with lectures.

The evaluation of the student consists in an oral exam , partially carried out in a written form, evaluated and discussed on the same day. Topics developed in class are proposed during the exam and the student must demonstrate a basic knowledge of the topics (cc3) and be able to correlate the structure, properties and production processes of materials (ca3).
