NONLINEAR DYNAMICS OF CLOSED CYLINDRICAL SHELLS UNDER THE ACTION OF LOCAL TRANSVERSE LOADS
Abstract
The closed cylindrical shell finite length under the action of constant at time and alternating local transversal loads in the context of nonlinear classical theory of gentle shells is consider. The equations in partial derivative are reduce to the combined of ordinary differential equation at times (the problem Koshi) using Bubnov-Galerkin's method as a higher approximation in Vlasov's form. The combined of ordinary differential equations is solved Runge-Kutt's method of the fourth order. The convergence of Bubnov-Galerkin's method is analyzes. The dynamical critical loads under the action unlimited impulse at time for conservative system (ε = 0) and alternating transversal load for dissipative system (ε = 1) in depending on quantity of members expansion series are finding
