Programma dettagliato e risultati di apprendimento attesi

 Objectives and synthesis of the subjects

The aim of the course is the introduction of the fundamental concepts of design, sizing, assessment of strength and life evaluation of aeronautical components. The study will start with a general description of the most used mechanical components for aeronautical applications (shafts, bearings, gears, frames, etc.) and of the methods of jointing (rivets, welding), with the definition of principles and methodologies for its detailed design. After this first introduction, will be considered the different design methods applied for the aeronautical structural elements (Safe Life, Fail Safe, Damage Tolerant and Flaw Tolerant).

In addition, the knowledge related to the mechanical behaviour of materials, with particular attention to the fatigue behaviour, will be analysed and the different methods to take it into account will be explained (high cycle fatigue, variable amplitude loading fatigue, damage calculation, nucleation and propagation of cracks, presence of defects); after this, the main formulation for the structural integrity assessment will be shown (static and fatigue assessment, multiaxial state of stress, etc.).

Several applications of the previously defined concepts will be carried out, with also experimental application.

 

Brief description of the subjects

Main topics are:

- functional description of the most common machine elements with aeronautical application (shafts, bearings, gears, frames, riveted and welded joints);

- fatigue design methodologies (Safe Life, Fail Safe, Damage Tolerant and Flaw Tolerant);

- mechanical behaviour of materials (static and fatigue behaviour, variable amplitude loadings, nucleation and propagation of cracks, defects);

- structural integrity assessment (static and fatigue assessment, multiaxial state of stress);

- application on mechanical and aeronautical components.

 

Course organization

Lessons and practices: lessons and practices, integrated together, will be developed during the course

Experimental labs: during the course, some experimental lab experiences on aeronautical components and systems will be carried out. A report on the labs experiences is requested and is compulsory.

 


Note Sulla Modalità di valutazione

 

The exam is composed by a written exam with exercises and theory questions, and a facultative oral exam selected by the student.
