Course detail

Limit States of Structures II

FSI-RMLAcad. year: 2026/2027

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.
