Course detail
Limit States of Structures II
FSI-RML Acad. year: 2026/2027 Summer semester
The course Limit States of Structures II expands the knowledge base of the preceding course Limit States of Structures I. It focuses on several significant aspects of engineering practice from the perspective of service life assessment under dynamic loading, advanced assessment of defect types such as cracks (the "damage tolerant" concept), and the service life assessment of polymers and polymer composites.

Entry knowledge
Static structural analysis of beam bodies.
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.
Fatigue assessment of components without cracks and with cracks.
Rules for evaluation and completion of the course
The graded credit consists of active participation in the exercises (preparation of documentation and a semester project) and a written part in the form of test questions.
Participation in the exercises is mandatory. Non-participation can be compensated for by completing the exercise assignment and demonstrating knowledge of the topic covered. Longer absences are compensated for by a special assignment according to the instructions of the instructor or lecturer.
Aims
The aim of the course is to expand the knowledge base in the field of limit state assessment, i.e., to build on the RMK course. More specifically, it aims to familiarize students with other important areas of strength and durability assessment of structures. These include the dynamic response of structures and the subsequent assessment of resulting deformation and stress states, advanced assessment of crack-type defects (the "damage tolerant" concept), and assessment of the service life of polymers and polymer composites.
