CALCULATION OF ELASTICITY MATERIAL CONSTANTS BY OWN VIBRATION FREQUENCY OF ROUND PLATE

Full Text:

Abstract

The paper analyses existing methods for determination of elastic material properties and reveals perspectives for usage of resonant methods which make it possible to execute a non-contact and non-destructive control. As an example of a resonant method application a problem on determination of elastic material properties by own vibration frequency of a specimen in the form of a round plate is considered in the paper. Solution efficiency of the investigated problem using a gradient-search method is given in the paper.
