Vibrations refer to periodic oscillations or movements of an object or system around a certain equilibrium position. This research area involves the study of the behavior and characteristics of these vibrations, including their frequency, amplitude, and damping effects. Researchers in this field investigate the causes and effects of vibrations, as well as potential applications in various industries such as engineering, aerospace, and structural design. Studies in vibrations often involve mathematical modeling, experimental testing, and analysis to better understand and control these dynamic phenomena.
