The superposition theorem is the cornerstone of linear system theory, which enables the study of the dynamic behavior of linear systems, both analytically and numerically. It is precisely this theorem which, by allowing modal analysis, capitalizes on the concept of normal modes of motions and render

Many weakly non-linear structures exhibit normal modes that are analogous to linear modes of linear oscillatory systems. As in the testing of linear modal systems, optimal sensor and actuator placement is important for obtaining the best test results. Such optimal placement is also important in cont
