Training objectives
- To provide the student with extensive knowledge of mechanics of materials and structures for machine design.
Prerequisites
- Principles of machine design and linear elastic stress analysis.
Course programme
- Structural Integrity A
Strain analysis. Constitutive equations and linear elasticity. Monoclinic, orthotropic, transversely isotropic and isotropic material. Principle of virtual works. Weak form of the equilibrium problem for ana elastic body. Properties of the solution. The force method and the displacement method of structural analysis. Kirchhoff-Love plate theory. The course will include classroom exercises sessions and computer-lab sessions that will permit interactive computer exercises and group discussion on the representation of deformed configurations and elastic properties.
Structural Integrity B
Three-dimensional stress analysis. Multiaxial high cycle fatigue.
Fracture mechanics in materials and mechanical components. Fracture mechanics for fatigue.
Buckling instability: buckling of slender columns, local buckling in thin sheet, real structures instability.
Exercise and training on real mechanical problems. Didactic methods
- Theoretical/practical lessons.
Learning assessment procedures
- Structural Integrity A
The examination is divided into two parts: a written exercise requiring the solution of a hyperstatic plane frame and a oral exam consisting of few questions about the course contents.
Structural Integrity B
The examination takes place in 2 separate sessions:
- the written session consists in the numerical solution of two or three exercises or numerical application of topics of the course program
- in the oral session, the student is asked to explain and discuss one or two of the subjects of the course. Reference texts
