ABSTRACT

The equations of dynamics of elastic shells subjected to large deformations are formulated. The Eulerian coordinates on a circular cylinder and time are accepted as independent variables, and one of the unknown functions is the distance from a point of the shell surface to the cylinder axis. The equations of dynamics of nonlinear elastic shells in the Eulerian coordinates are convenient for exact formulation of the problem on the interaction of flexible shells with moving fluids and gases. The equations obtained can be used for dynamic calculations of fluids and gases flows in pipelines, blood vessels, hoses, and other nonlinearly deformable thin-walled tubular elements of constructions.
