Learning Objectives
The aim of the course is to provide the student with fundamental knowledge on the mechanical properties of materials, on measurement methods, on correlations of material properties with the microstructure and the production technologies.
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 materials and production methods in order to define a product and its characteristics. The technologies for their production.
Application ability: ca3-Applying knowledge and understanding related to the most appropriate methods of analysis, modelling, verification of components and mechanical groups subjected to static and fatigue stress; analysis of the characteristics of metallic, ceramic and polymeric materials for the production; the choice of the best production process aimed at the creation of components; analysis and design of production systems including the study of reliability, safety and economic and environmental sustainability.
The following transversal competencied will be developed in the course:
CT1 Written technical communication (reports, deliverables)
CT3 Development of an adequate expression and technical discussion of own arguments
CT4 Graphic representation and communication (drafting of diagrams, graphs and tables)
CT5 Understanding of technical standards
CT7 To respect commitments and deadlines
Prerequisites
Chemistry and physics basic knowledge
Teaching Methods
The course is hold by lectures.
Type of Assessment
The evaluation of the student consists in an oral exam. 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).
