Learning outcomes Identify the properties of different types of materials, their processing techniques and know how to present examples of typical applications.
Apply material selection concepts, the most appropriate processing methods in simple and compound products.
Develop eco-selection, introducing energy concerns, stimulating the reuse and valuation of materials.
Apply the design concepts of structures and joints to design the final geometry of a solid system, according to the selected materials.
Syllabus Introduction: Importance of the mechanical design; Design Phases
Materials in the design: evolution of materials; Classification of materials; Properties of materials.
Selection of Materials: selection strategies; Material selection and consequent environmental impact of the product.
Materials production processes: material removal processes; Casting Sintering Injection and extrusion; Plastic forming; Composite materials processes.
Free Body diagram: Statics review; Internal loads;
Component dimensioning: stress and strain analysis; Stress concentration.
Dimensioning of connections without relative movement: pressure connections with interference; bolted connections; Welded and glued bonds.

Teaching Methodologies and Assessment Criteria i) Research and synthesis work – 50% individual work.
-Development of a project, including material selection and dimensioning calculations of components and connections. Selection of a system/equipment/functional device. Conducting a report and its discussion.

The evaluation will take into account: attendance, interest, proposals for improvement, autonomy, depth of approach to the topic.

II) written Individual evaluation test – 50%

To obtain the frequency rating and have access to the exam, the student must obtain the minimum score of 6 values.

In the exams will be considered the work of analysis and synthesis. That is, the written exam will be classified to 50%.
Language Portuguese. Tutorial support is available in English.
