Abstract

We develop a method for the digital-optical analysis of defects in materials with simultaneous measuring of several diagnostic parameters and estimation of the degree of damage to the material in the vicinity of a stress concentrator by analyzing the displacements and distortions of the preliminarily made surface marks. By using the results of mathematical description of the field of displacements on the metal surface, we propose to use informative signs for the quantitative analysis of the parameters of damage.
