At first glance few problems arise in the area of structural dynamics which cannot be solved by means of today’s experimental and analytical tools. Thus, the elastodynamic characteristics can be determined by using common experimental or analytical methods if structural linearity can be assumed to be a proper approximation. However, as experience has shown, the world of structural dynamics is not as linear as desired, which becomes evident when dealing with such problems as control mechanisms and wing/external stores connections of airplanes as well as related problems in spacecraft engineering and many other areas. Consequently, setting up dependable mathematical models requires special attention to nonlinear effects, including modifications of linearized standard procedures.
