Arnauta N. Axisymmetrical nonstationary problems of the theory of multiplayered stiffened shells of revolution with allowance of discrete ribs

In the framework of the Timoshenko type non - linear theory of shells and ribs nonstationary vibrations multilayered shells of revolution with allowance for discrete ribs are investigated. Reissner's variational principle for dynamical processes is used for deduction of the motion equations. An efficient numerical method with using Richardson type finite difference approximation for solution of problems on nonstationary behavior of multiplayer shells of revolution with allowance for discrete ribs which permit to realize solution of the investigated wave problems with the use of personal computers, as well as bringing their solutions to receiving concrete numerical results in wide diapason of geometrical, physico - mechanical parameters of structures are elaborated. On the basis of the offered model nonstationary problems of the forced nonlinear vibrations of multilayered shells of revolution of varios structure are solved and analysed.
