The course aims to provide students of the knowledge and understanding of the criteria of structural design
for static strength
The course aims to provide students of the knowledge and understanding of the criteria of structural design
for static strength
The course aims to provide students with methodologies and analytical tools for the study of the state of tension / deformation in solids and structures for the purpose of evaluating resistance in the static field, with particular reference to the mechanical elements attributable to the "beam ".
Attendance to lectures and guided exercises and individual study will allow the student to:
The lectures, together with the development of numerous exercises, also in the form of guided exercises, provide the student with a logical and orderly method to follow in the applications of the theory. All the examples / exercises solved use this methodology in order to favor a good assimilation of the theoretical principles, proceeding step by step from the simple example to the more complex and articulated one. The student also achieves a good experience in solving various problems. Starting from the fundamental concepts of stress and strain, the student are encouraged to analyze the experimental behavior of materials, with special reference to materials typically used in engineering, by using photos, experimental samples, videos.
Mechanics of solids and structures: forces and moments; equilibrium of deformable body; articulated assemblages of rigid members
Stresses and strains in solids . Principal stresses . Mohr's Mohr's circle plane stress
Special problems of structural mechanics: Beam theory
Materials: Steels and Cast irons; Classification.
Mechanical properties of materials: tension and compression test; stress-strain diagram; stress-strain behavior of ductile and brittle materials; Hooke's law; Poisson's ratio; shear stress-strain diagram.
Axial load: Saint-venant's Principle; Principle of superposition
Torsion: torsional deformation of a circular shat, angle of twist; solid noncircular beams; thin-walled bams
Bending: shear and moment diagrams and graphical method for constructing ; bending deformation of a straight member; flexure formula; unsymmetric bending
Transverse shear: shear in straight members; shear formula
Static strength of materials. Ideal or equivalent stress. Strength criteria for ductile materials. Safety condition: Limit stress, Safety factor, Admissible stress.

All class schedules are posted on the EasyAcademy portal.
The exam includes a written test and an oral test.
The written test consists of an exercise to be solved within 2 hours. During the test, only the use of the calculator is allowed. Smartphones have to be switched off.
Those who obtain a score of at least 18/30 for the written test can access the oral exam. Those who do not pass the written test have to repeat it in any official scheduled date.
The oral exam, which can be held within a calendar year after passing the written test, includes two questions: questions relating to the theoretical part developed during the lessons and / or the written test, as a critical comment.
A failed oral exam does not invalidate the written test which can be reused in the future (within one year).
The final mark is given by the average of the marks of the oral and written tests: if it is a decimal, it is rounded to the upper unit.
The written test assesses the student's ability to:
The oral exam focuses on the topics faced during the lectures and aims to assess to which extent the student:
