Prerequisites:

Calculus, equilibrium, work and energy, temperature, systems of forces, conservative systems. Stability of equilibrium. The contents of the courses of mathematical analysis, physics and rational mechanics. Students have to have passed all exams of year 1 and at least exams for 75 CFUs in the fist two years. 
Target skills and knowledge:

Basic concepts of structural mechanics and in particular of beams. Stress state and strain state in a point of a body. Equilibrium written as zero virtual work. Structural failure due to insufficient strength, to instability or to fatigue. Examples will be taken also from aerospace applications. By the end of the course students will be able to classify a structure as statically determinate, redundant ..., compute stress and strains in planar beam systems and evaluate various types of structural failure. 
Examination methods:

The written exam tests both the capability to solve structural problems and to answer theoretical questions. Students cannot use any supplementary materials, such as books or hand written notes, during the exam. The two exercises assess the student's capabilities to solve structural problems involving 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 exactely all paper exercises and answer correctly to all theory questions. 
Course unit contents:

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 Venant's problem, failure criteria, equilibrium stability, Euler's beam, fundamentals on fatigue. 
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 (orario di ricevimento). Many examples are completely worked out in class. 
Additional notes about suggested reading:

The two books by Lenci and Galvanetto cover all topics of the course except for 'freely pinned structures', statically determinate and undeterminate, and for fatigue phenomena. Lecture notes on these last topics are provided.
