Документ Application of a superparametric finite shell element to the calculation of turbine blade vibrations(Kluwer Academic / Plenum Publishers Corporation, 1982) Bogomolov, S. I.; Lutsenko, S. S.; Nazarenko, S. A.Determination of the natural frequencies and forms of vibrations of turbine blades with the present level of knowledge is one of the chief problems that have to be solved at the design stage of turbines in order to ensure vibration reliability. Greater possibilities of devising more correct mathematical models of blades and universal methods of investigating their vibrations are opened up in connection with the application of the finite element method.Документ Numerical modeling of dynamics of sandwich plates with partially damaged facesheet-to-core interface(Apostrophe, 2011) Burlayenko, V. N.; Sadowski, Tomasz; Nazarenko, S. A.A finite element (FE) model has been developed for analysis of the dynamic response of sandwich plates with partially damaged facesheet-to-core interface. The effect of intermittent dynamic contact between the fragments detached at the damaged interface is taken into account in the vibrating sandwich plate. The general mathematical statement of such non-linear elastodynamic problem for a cracked body is first formulated. Numerical results for the transient and steadystate dynamic responses of a foam-cored sandwich plate damaged by debonding are obtained by using the ABAQUS code. The influence of the strongly nonlinear local contact behavior on dynamics of the sandwich plate is examined.
