Description and Objectives
This course is dedicated to the review and further development of notions of mechanics of materials addressed in the
courses CVG2140/2540, including stress, strain, and constitutive laws for linear elastic materials; tension and bending of
symmetric beams; torsion of circular bars; statically determinate and indeterminate systems; thin-walled pressure vessels;
stress concentration factors. This course aims at providing through understanding of these notions.
The notions above will be generalized by addressing non-symmetric beams and prismatic bars; thick-walled pressure
vessels; buckling; material response beyond the elastic regime; residual stresses; failure criteria in static loading fatigue;
impact stresses; energy methods and Castigliano’s theorems. A brief introduction to the finite element method will be
also provided.
Exams and Assignments
Exams: All exams will be open book - open notes.
Illegible work and loose sheets will not be graded. If a student cannot attend a test/exam due to a medical condition,
certified by a doctor, he/she must notify the instructor in advance. Unexcused absence from an exam will result in
a grade of 0 for that exam.
Mid-term exam Wed, July 16 - 12:00 - 14:00 in CBY B012
Final exam July 31 - 18:00 - 21:00 in STE B0138
Assignments: Four homeworks will be assigned during the term. Assignments will be individual. There will be tutorial
sessions dedicated to problems solving based on the material presented during the lectures.

Syllabus
Grades
Grades from assignments and mid-term exam determine the semester grade S, computed as follows:
Mid-term exam
Homework assignments
Total of semester (S)
60%
40%
100%
This mark will be combined with the final exam grade F in the following way:
0.6F + 0.4S
If F < 55%, regardless of the mark of the semester S the overall course grade will be F.
