Dynamic interaction of a thin cylindrical shell with a viscous liquid

Abstract

Based on the principle of the possible displacements in an axially symmetric formulation, the dynamic interaction of a circular cylindrical shell with a viscous compressible liquid under nonstationary loading by a rectangular pulse is studied. The problem is solved using an orthonormal system of basis functions obtained by applying a Gramm-Schmidt algorithm to an initial nonorthogonal system of basis functions. Results from numerical studies are presented. Solutions using nonorthogonal and orthogonal systems of basis functions are compared.
