Aerospace engineering

Recalls on the concepts of stress and strain states, aerospace materials, brittle and ductile, isotropic and orthotropic, Mohr's circle and its use Resistance design: failure criteria for isotropic materials: maximum stress, maximum strain, maximum strain energy, maximum distortion energy, Mohr's criterion Fatigue design: fatigue for isotropic materials: recalls, definitions, parameters influencing fatigue behaviour, Wholer, Soderberg and Goodman-Smith diagrams. Miner's rule. Design criteria for an aerospace fatigue structure Chip removal machines and related tools: lathes, milling machines, drills Plastic processing for isotropic materials hot and cold rolling Hot and cold extrusion (direct and reverse), drawing, deep drawing, forging Hammer and press working Joints: mechanical fitting (screws, bolts, rivets), riveting techniques, welding techniques, structural bonding Composite materials: fibres and matrices of aerospace interest, thermoplastic and thermosetting resins Composite materials processing techniques: lamination, filament and tape winding, pultrusion and moulding, RTM and RFI techniques Micromechanics of composite materials Macromechanics and classical laminate theory Failure criteria for composite materials: maximum stress, maximum strain, Tsai-Wu, Tsai-Hill Non-destructive testing: ultrasound, thermography, shearography, X-ray, laser interferometry, etc. Innovative manufacturing technologies: metal powder and composite additive manufacturing, automated layer positioning, out-of-autoclave curing techniques

There are no mandatory prerequisites, but good knowledge of solid mechanics and structures is recommended.

Lecture notes provided by the instructor are available on the e-learning platform at the following link: https://elearning.uniroma1.it/course/view.php?id=14761 and on the website of the Aerospace Engineering Area Council, cover all the topics addressed in the course.

The course is based on frontal lessons, partly focused on theoretical aspects and partly on descriptive concepts of the different production processes. The theoretical lectures are interspersed with numerical exercises in which the concepts learned are applied to case studies concerning aerospace issues. Lectures are supported by film screenings, viewing of various materials and supplemented by visits to the laboratories.

The attendance is not mandatory but highly recommended.

The course exam will be conducted solely through a written test. The written test consists of two parts: the first part is theoretical/numerical and concerns an exercise on the verification of static and fatigue strength of a component; the second part consists of a series of questions on the topics covered in the course. Access to the second part of the exam will be granted only after achieving a passing grade in the first part.
