Installation of holographic analysis of residual stresses

Purpose: Holographic interference measurements in the deformable solid experimental mechanics field.

Stand for holographic interference measurements in the deformable solid experimental mechanics field, material mechanics, including composite materials based on coherent-optical methods for studying deformations.

For testing and research at the stand, the methods have been developed that use holographic interferometry and speckle interferometry:

- for residual stresses registration;

- for structural elements (including interacting with a liquid medium) vibration characteristics determination;

- for various types materials (isotopic, anisotropic, multimodular, viscoelastic) elastic properties determination, as well as the properties of materials under conditions of microplastic deformation and microcree.

Specialized small-sized installations based on an electronic speckle interferometer can be created to study the structural materials properties and register residual stresses in production (field) conditions.
