Head Kubenko Veniamin Dmitrievich, Registration Date 02-02-2012 Organization S.P.Timoshenko Institute of Mechanics popup.description2 The procedure of numerical investigation nonstationarity non-linear dynamic processes in hydrodynamic system cylindrical orthotropic shells with a proceeding fluid is developed and realized. The procedure is grounded on the theory of fluid potential fluxion of and the theory of thin elastic shells. With use of this procedure are analyzed kinematical performances of the peak amplitudes of non-linear oscillations in transient process of a shell subject to local in space and the harmonic in time loads. It is erected that quantities of the peak sags of a shell in the non-stationary regime can essentially exceed their values in a mode of steady state oscillations.
