What is it about?
The materials currently used in modern structures do dramatically change their mechanical properties under the influence of low operating temperatures. One of the factors affecting the breakdown of various structural elements at low temperatures, is the placement of the stress concentrations. The existing analytical design schemes cannot always correctly take into account the material mechanical properties changes caused by the temperature decrease. In the present work we consider the method of contact holographic interferometry, which made it possible to efficiently determine surface displacements and strains at the temperature of –50 °C.

Why is it important?
For the first time, the possibility of conducting off-table tests of the samples at low climate temperatures using holographic interferometry was experimentally confirmed.
Perspectives
The IOM preparation methods have been developed that ensure the stability of the optical-mechanical properties of the interferometer over the entire range of recorded displacements under various climatic temperatures.
