Syllabus

Prerequisites:	None
Target skills and knowledge:	The Course presents the theoretical background of the finit element method for structural design, the linear elastic fracture mechanics, the theory of thick shells and stability of equilibrium. The theory is applied to several practical examples and exercises.
Examination methods:	Discussion and evaluation of the project (0/3 points) Written examination-first part: three exercises, maximum three hours (max 30 points) Written examination-second part: three questions concerning theory, maximum 45 minutes (max 30 points) Score of the written examination: (ScoreExercises + ScoreTheory + ScoreProject)/2 Oral examination only for students having a score of the written examination equal to or greater than 26. Final score ie the average between the scores of written and oral examinations
Assessment criteria:	The discussion of the project evaluates the skills of the student to use a commercial software package to solve a practical structural design and the quality of the written technical report. The written examination with three exercises evaluates the ability to solve a practical structural strength assessment problem by using the appropriate theory and by performing calculations correctly. The written examination with three questions of theory evaluates the knowledge of demonstrations concerning the different theories, along with their limitation of applicability. the oral examination evaluates the appropriateness of the technical language and the methodological adequacy in presenting the theoretical topics.
Course unit contents:	The finite element method in structural design. Linear Elastic Fracture Mechanics for static and fatigue strength assessments. Non conventional extensions of the linear Elastic Fracture Mechanics: Notch mechanics; Williams solution of sharp V-shaped notches. Strain energy density at V-notch tips: application to fatigue analysis of welded structures. Thick-walled tanks, rotating discs. Natural frequencies and critical speeds of shafts. Practical project on a structural design problem using a commercial finite element software package.
Planned learning activities and teaching methods:	Two lectures and one exercise class per week. Individual project.
Additional notes about suggested reading:	Beside the texbooks, the teaching material consists also on lecture notes and scientific papers.
