FSI-6MSAcad. year: 2022/2023
Designing machines, vehicles, and structures that are safe, reliable, and economical requires both efficient use of materials and assurance that structural failure will not occur. It is therefore appropriate for undergraduate engineering majors to study the mechanical behaviour of materials, specifically such topics as deformation, fracture, and fatigue. This course reviews also micromechanics and micromechanical aspects of brittle fracture, fatigue failure and creep rupture. Fracture mechanics. Application of fracture mechanics for integrity assessment of machine parts and structures with cracks under static, cyclic and creep loading. The influence of size effect and loading conditions on fracture toughness of materials.

Assesment methods and criteria linked to learning outcomes
The graded course-unit credit is awarded upon the following conditions: participation on all exercises, elaboration of protocols according to the teacher’s instructions and passing through a test succesfuly. Test consists of two parts: (i)theoretical item, (ii) an examples solved during the exercises. In this part of the test is allowed to use the notes from the lectures, as well as protocols of exercises.
Examination: The exam consists of two parts: (i) written and (ii) oral. In the written part of the exam the student elaborates three questions: (i) theoretical item, (ii) an example solved during the exercises. In this part of the exam is allowed to use the notes from the lectures, as well as protocols of exercises. In the oral part the student explains the theoretical item and describes the way of solving the examples, including relationships and assumptions he/she has utilized.
