Course detail
Limit States of Metallic Structures
FSI-RMKAcad. year: 2024/2025
Limit states - their general classification, limit states in strength analysis. Fatigue of structures, basic characteristics, durability assessment of service life under low-cycle and high-cycle fatigue. The most important concepts of linear-elastic and elasto-plastic fracture mechanics. Evaluation of the resistance of structures to brittle failure at the stage of their design. Assessment of the crack as a defect under monotonic and cyclic stresses.

Entry knowledge
Empirical calculation of machine parts.
Static structural analysis of parts using finite element method.
Material characteristics of metallic materials (without a crack and with crack) in terms of monotonic and cyclic loading and also in terms of reduced, normal, and elevated temperature.
Rules for evaluation and completion of the course
Attendance at seminars is mandatory. A one-time absence can be replaced by exercising with another group in the same week or by working on a substitute assignment. Prolonged absence is replaced by a special assignment according to the instructions of the instructor or lecturer.
Aims
Gaining an overview of the limit states during the design and assessment of metal structures. In further technical practice, graduates will be able to specify the individual steps of assessment according to the necessary regulations, standards or guidelines.
