Investigation of the parametric vibration of the orthotropic plates subjected to periodic in plane forces by multi-modal approximation and R-functions method / J. Awrejcewicz, L. Kurpa, O. Mazur // Nonlinear Dynamics–2010 = Нелинейная динамика–2010 : proceedings the 3rd International Conference, dedicated to the 125th Anniversary of the National Technical University "Kharkov Polytechnic Institute", September 21-24, 2010 / National Technical University "Kharkov Polytechnic Institute" [et al.]. – Kharkov : NTU "KhPI", 2010. – P. 256-260.https://repository.kpi.kharkov.ua/handle/KhPI-Press/37138The original method of studying parametric vibrations of orthotropic plate with complex shape is proposed. Suggested approach is based on combined application of variational methods and the R-functions theory. Using the proposed method and developed software the regular and chaotic regimes of T-shaped plate are analyzed.enThesis
