FIELD: physics, measuring.
SUBSTANCE: invention concerns examination of strains and deformations and can be used for examination of strains and deformations in details, for example, in devices of metal constructions of engineering constructions. On explored surface of detail superimpose fragile strain-sensing coat. In addition carry out installation of the module with data units of transformers of an acoustic emission. As a fragile coat use a coat on the basis of the artificial tars, containing resorcinol-formaldehyde tar of SF-282 with addition of carbamide-formaldehyde concentrate CFC-85. As a hardener of the liquid carbamide-formaldehyde concentrate use a water solution of formalin, ethyleneglycol and carboxymethyl cellulose, and hexamethylenalnine.
EFFECT: increase of accuracy and efficiency of examination.
