摘要: Three nonlinearities are considered. They structural for plates and shells, fluid mechanical bluff body oscillators, aerodynamic airfoils in transonic flow. For aeroelasticity of the equations motion well established. Results obtained by numerical time integration may be compared to those topological theories dynamics also from experiment. All these suggest that chaotic limit cycle oscillations occur this deterministic system. In a later chapter, systems discussed broader context. themselves still an emerging stage. Here qualitative theory useful establishing generic model describes essential features physical phenomena. flow effective methods analysis under development based on first principles solid mechanics, results exploratory studies now becoming available. An introductory discussion is contained chapter fuller treatment provided following chapter.
