Numeryczne rozwiązanie zagadnienia stateczności dynamicznej płyt pierścieniowych

Stanisław Wojciech

A solution obtained by the finite difference method of the annular plate dynamic stability problem has been presented. To obtain the solution it has been assumed that the preliminary plate deflection and the additional deflection due to the load are axisymmetric. The plate has been loaded by uniformly distributed, along edges, radial forces increasing linearly in time. The effcct of the assumed discretisation points number on the accuracy of results as well as the effects of the magnitude of preliminary deflection the way of support and velocity of the load increase on the plate deflection have been investigated.
