Forced Nonstationary Vibrations of a Sandwich Cylindrical Shell with Cross-Ribbed Core

The equations of nonaxisymmetric vibrations of sandwich cylindrical shells with discrete core under nonstationary loading are presented. The components of the elastic structure are analyzed using a refined Timoshenko theory of shells and rods. The numerical method used to solve the dynamic equations is based on the integro-interpolation method of constructing finite-difference schemes for equations with discontinuous coefficients. The dynamic problem for a sandwich cylindrical shell under distributed nonstationary loading is solved with regard for the discreteness of the core__________Translated from Prikladnaya Mekhanika, Vol. 41, No. 2, pp. 60–67, February 2005.

Numerical solution of problems in the dynamics of ribbed shells of revolution

We consider dynamic processes in shells of revolution reinforced with discrete ribs. The stress—strain state of the shell is determined in the framework of the linear theory of Timoshenko elastic thin shells. The ribs are described using the theory of curvilinear rods. The system of differential equations is solved by applying the variational principle to nonstationary problems.S. I. Subbotin Institute of Geophysics of the Ukrainian Academy of Sciences.
