Transverse Vibrations and Stability of Systems with Gyroscopic Forces
Source abstract
Abstract
Abstract It is well known that third order elastic constants in bulk materials can be determined from acoustoelastic measurements. Modifications are needed to these techniques to obtain higher order,e.g fourth order elastic constants. In this paper, methods will be suggested 10separate second order nonlinearities (related to fourth order elastic constants) from the stronger first order nonlinearities. These methods include modifications of acousto-elastic results by appropriate choice of polarization and harmonic analysis. It hasbeen shownthat second order nonlinear measurements are more sensitive to detect weak boundary layers in an adhesive joint than linear measurements.
