Prerequisites
Basic knowledge of solid mechanics
Learning outcomes
KNOWLEDGE AND UNDERSTANDING:The course aims to provide knowledge to the design and testing of machines and complex mechanical systems. In particular, it intends to transfer the most advanced concepts of mechanics of materials, from the fracture mechanics to plasticity and creep, even in triaxial stress state. Analytical calculation methods are proposed for components subject to complex loadings, such as plates, disks and tubes, in order to achieve the theoretical basis of advanced structural mechanics
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:The student will gain the ability to use the techniques and tools appropriate to address complex engineering problems, in order to be able to correctly interpret the causes of structural and technological behaviours. The acquired skills will allow the student to face the articulated mechanical systems projects, identifying and applying the most suitable calculation method for the analysis and design of machine components; the ability to solve typical problems of mechanical design, including structural optimization, will be transferred to the student
TRANSVERSAL SKILLS:The resolution of exercises that will be conducted during lessons will help improve the ability to solve engineering problems. The execution of a short thesis and its discussion will allow the students to develop the ability to articulate and implement their ideas in a technical context and to present the results of their work in a clear form.
The students will also acquire the ability to deal with a complete design problem, from the choice of the material and of the global structure, to the design and analysis of the main mechanical components, integrating the various multidisciplinary knowledge acquired during the studies
Program
First part: Mechanical behaviour of material: plasticity, linear elastic and elasto-plastic fracture mechanics, creep, low cycle fatigue. Second part: structural analysis of discs, pipes, plates and shells.
Development of the examination
LEARNING EVALUATION METHODSWritten and oral examinations, and a brief thesis work
LEARNING EVALUATION CRITERIAIn the written test, the student must demonstrate the ability to solve three design and/or verification questions, with the help of the formulas and mathematical tools presented during the lectures. In the oral examination, the student must answer one or two questions, showing that he had learned the main concepts and the theoretical basis of advanced structural mechanics.
LEARNING MEASUREMENT CRITERIAA mark out of ten will be given to each of the three tests.
FINAL MARK ALLOCATION CRITERIAThe final mark will be sum of the votes of the written, oral and brief thesis tests.
