Abstract
Approximate formulas are given for the determination of natural frequencies and maximum deflections and stresses in rectangular plates subjected to normal transient loading as well as to static loading. The stresses and deflections resulting from dynamic loads are obtained by the application of a “load factor” to the values computed for a static load. The appendixes give the small-deflection theory of forced vibration of plates with approximate solutions for plates with edges which are clamped, simply supported, or free. It is assumed that the plate deflection may be expressed as a series, each term having the form of the normal-mode function of a uniform beam.
