Transient dynamics is a branch of engineering and physics that deals with the behavior of systems during the short periods of time immediately following a change in their operating conditions. This field focuses on understanding the temporary responses of systems to sudden disturbances or changes, such as impacts, vibrations, or sudden changes in temperature. By studying transient dynamics, researchers aim to predict and control the behavior of systems during these dynamic events, helping to optimize the performance, stability, and safety of various structures and systems. This area of research is important in many applications, including aerospace, automotive, civil engineering, and mechanical systems.
