Prerequisites:

The exam course on aerospace structures of the BEng degree.
Kinematics of rigid bodies, statics of rigid bodies, virtual work principle, kinematics and statics of deformable bodies, linear elasticity, solution of statically determinate structures, MNT diagrams, engineering theory of beams, symmetry, freely pinned structures, both statically determinate and undeterminate, force and displacement methods, virtual work theorem, displacement method applied to planar beam systems, rotation method. De Saint Venenat's problem, failure criteria, equilibrium stability, Euler's beam, fundamentals on fatigue. 
Target skills and knowledge:

Advanced topics in structural mechanics, in particular beams with thin walled cross sections and plates. The finite element method. Laminated composites. By the end of the course the student will understand the role played by the different structural elements of aerospace structures and will be able to evaluate strain and stress states in simple structural elements. Moreover s/he will be able to critically evaluate numerical models to study complex structural elements. 
Examination methods:

The written exam tests both the capability to solve two structural problems and to answer three theoretical questions. The two exercises assess the student's capabilities to solve structural problems involving thin walled beams. The theory questions assess her/his understanding of the theoretical foundations. An oral exam may follow the written exam if the student wants to improve her/his mark.
Exercises and theory questions are assessed separately. Students have to obtain at least 18/30 in both parts of the written exam to pass the exam. The theory question mark, weight 1/3, is added to the exercise mark, weight 2/3, to form the written exam mark.
• If the written exam mark is between 18 and 27 it will usually be the final exam mark
• If the written exam mark is above 27 the student is invited to sustain an oral exam to confirm (increase or decrease) the mark. If the student sustains the oral exam that will determine the final exam mark, otherwise the final exam mark will be 27.
• In the case of written exam mark below 18, or of failure at the oral exam, the student will have to take again the written exam. 
Assessment criteria:

The pass mark is awarded to students who have a correct approach to problem solving and theory. Full marks are given to students who solve perfectly all paper exercises and answer correctly all theory questions. 
Course unit contents:

Different types of aerospace structures, loads on aeronautical structures, airworthiness. Thin plates  Structural instability  Bending, shear and torsion of multicell thin walled structures  Classical laminate theory  Sandwich panels  dynamics of structures with vibrating base  launch induced excitation  main loads in orbitating satellites  buckling and postbuckling of plates, stiffened panels and thin walled beams  the finite element method, beam elements, plane elements, plate elements, 3d elements. 
Planned learning activities and teaching methods:

Learning is based on attending the lectures, 72 hours, and on the subsequent study of the relevant books. Students often meet the lecturer at given times (ora di ricevimento). Teaching is traditional with tablet projected on a screen. Many examples are completely worked out in class. 
Additional notes about suggested reading:

Megson's book is well known in the world for aerospace structures.
