The equations of the vibration of elliptic cylindrical sandwich shells with equally spaced stringers under nonstationary loading are derived. Models based on the Timoshenko-type shell theory are used. The dynamic equations are solved numerically by the integro-interpolation finite-differencing method for equations with discontinuous coefficients. The dynamic problem for an elliptic cylindrical sandwich shell reinforced with stringers is solved
