Critical Damping in Certain Linear Continuous Dynamic Systems.
Abstract
The most commonly used formulas for the analysis of fiber-reinforced and laminated beams are those given by the familiar 'law of mixtures'. In their most general form, these formulas are derived by the methods of elementary strength-of-materials theory, on the basis of the Bernoulli-Euler assumptions. In general, of course, these formulas are only approximate: for example, when calculating the deflection of the simplest type of laminated beam, namely a sandwich, it is known that the inclusion of the effect of shear is essential. Because of their simplicity, however, it is desirable to use them whenever one may do so with sufficient accuracy. It is therefore the purpose of the present work to examine the validity of the simple formulas, and to determine how, and when, they should be corrected. (Author)
