Abstract
Results of application of methods of holographic interferometry, electron speckle-interferometry and shearography for nondestructive quality control and determination of residual stresses in elements and members of the welded and adhesion-bonded structures made of metallic and nonmetallic materials are presented. To make diagnostics of structures, the compact holographic schemes and devices have been designed and manufactured with the help of which the local fields of displacements and deformations in the zones of defects and relaxation of residual stresses are recorded. Examples of diagnostics of aircraft and machine-building structures using the holographic interferometry, electron speckle-interferometry and shearography are given.
Keywords: holographic interferometry, electron speckle-interferometry. shearography, nondestructive testing, residual stresses, computer processing
