Abstract: 

A solution of the problem on forced vibrations of a truncated conical shell with elliptic cross-section is considered in the case of nonstationary loading. The linear version of the equations of a Timoshenko-type shell theory in a non-orthogonal curvilinear coordinate system is obtained. A statement of the problem is given, and a numerical algorithm of its solving is elaborated. An example of the dynamical behavior of a conical shell is studied numerically.

Keywords: conical shell, elliptic cross-section, forced vibrations, non-orthogonal curvilinear coordinate system, numerical solution, Timoshenko-type theory
