VIBRATIONS OF ELASTIC SYSTEMS TAKING ACCOUNT OF ENERGY DISSIPATION IN THE MATERIAL

Abstract

An analytical and experimental investigation is presented of vibrations of non-conservative elastic systems in which the sources of energy dissipation is irreversible cyclic straining of the material. Modern methods of analysis of nonlinear vibrating systems are extended to treat problems of the flexural vibrations of long bars of constant and variable cross section, short barsAND TURBINE BLADES. Torsional vibrations of rods are also considered. Considerable attention is given to the experimental investigation of energy dissipation in the material. Several apparatuses are described and some of the experimental results presented. (Author)
