NONSTATIONARY VIBRATIONS OF ELLIPTIC CYLINDRICAL SANDWICH SHELLS REINFORCED WITH DISCRETE STRINGERS

摘要

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
