Prerequisites: Machine Design, linear algebra, differential and integral calculus.
Target skills and knowledge: The course aims to provide students with a proper knowledge on some topics of advanced mechanical design. In particular:
1. General methods for the stress analysis applied to linear and non-linear problems.
2. Design of pressure vessels and rotating discs
3. Advanced structural design methodologies for welded and bolted joints
4. Damage tolerant approach, fracture mechanics, defects and notch mechanics.
Examination methods: The expected knowledge and skills will be verified with a written exam, divided into two parts:
- 2 or 3 application exercises (for a total score of 10 points out of 30)
- 5 open questions (for a total score of 20 points out of 30).
The oral exam is optional and possible only for scores over 25. It is an oral interview with 2 or 3 open questions.
Assessment criteria: The evaluation criteria will be:
- Completeness of the theoretical knowledge acquired on the topics of the course
- Ability to apply the theoretical knowledge to the practical design of mechanical components (such as welded parts and bolts, flywheels, tanks, etc.)
- Exposure ability and rigorousness.
Course unit contents: • Introduction to the theory of elasticity and advanced stress analysis
• Design against buckling
• Design of thin walled pressure vessels, pressure pipes, rotating discs
• Stress analysis in componentes with holes and notches (Solutions by Kirsch, Inglis, Irwin, Williams, Lazzarin and Tovo)
• "Damage Tolerant Approach" to the mechanical design (Linear Elastic Fracture Mechanics)
• Design of welded and bolted joints with conventional approaches
• Fatigue design of welded joints with local approaches (NSIF, SED)
• Local approaches for static and fatigue resistance of notched components
• Material nonlinearity: constitutive models under static and cyclic loadings, stress analysis on mechanical components in the presence of localized plasticity
• Design against low cycle fatigue
• Introduction to anisotropic elasticity: symmetries of material and elastic models, notch effect in anisotropic materials
Planned learning activities and teaching methods: The course is structured into the following activities:
- Theory lectures in the classroom
- Exercise lectures in the classroom, with several examples of application
Additional notes about suggested reading: The fundamental teaching material consists of:
-written notes, including all the topics and exercises with solutions
- Further exercises with solutions made available to the students on the moodle platform.
- Further material (such as technical and scientific papers, etc.) made available to the students on the Moodle platform.
