A thorough understanding of the dynamics of rotating structures is the starting point for the study of fatigue effects, forced-response, and flutter instability, which occur in airplane engines, helicopters, and turbomachinery. Their modeling is usually made with beam models, which ensure, in many cases, accurate and reliable results with an affordable computational effort. According to the one-dimensional assumption, the three-dimensional problem is being split into two problems, which are defined, respectively, along an arbitrary (longitudinal) direction that typically has the predominant dimension and above its perpendicular plane (cross section). The unknowns depending on the longitudinal coordinate may be interpolated using both numerical and analytical mathematical techniques, while the behavior of those related to the cross section is...
