Выполнен анализ существующих методов определения упругих свойств материалов и показана перспективность использования резонансных методов, позволяющих производить бесконтактный неразрушающий контроль. В качестве примера использования резонансных методов рассмотрена задача об определении упругих свойств материала по собственным частотам колебаний образца в виде круглой пластины. Показана эффективность решения исследуемой задачи с помощью метода градиентного спуска.

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.
