Abstract

Random phenomena are widespread across disciplines such as Engineering, Physics, Geophysics, and Medicine, often arising from the inherent variability of natural systems. In Structural Mechanics, sources of randomness include environmental forces like wind, seismic activity, and manufacturing tolerances, which can induce vibrations with unpredictable features. While linear methods have traditionally been used to analyse such vibrations, they often fail to capture the complex behaviour that emerges in nonlinear systems.
