This volume gathers the latest advances and innovations in the field of structural dynamics, as presented at the International Conference on Structural Engineering Dynamics (ICEDyn), held in Lisbon, Portugal, June 23-25, 2025. The contributions cover a diverse range of topics, including digital twinning, rotating machinery, aeroelasticity, vibration control, substructuring and reduced-order models, data-driven diagnosis of machinery and structures, data processing methods, additive manufacturing for dynamic applications, modelling and analysis of dynamical systems, and the use of AI in different aspects of damage identification. Selected by means of a rigorous peer-review process, they will spur novel research directions and foster future multidisciplinary collaborations.
