METHOD OF RESISTIVE NON-DESTRUCTIVE TESTING Russian patent published in 2020 - IPC G01N27/20 

FIELD: construction.

SUBSTANCE: invention can be used for non-destructive inspection of condition of constructions, structures, mechanisms and machines experiencing static and dynamic loads. Substance of invention consists in fact that on extended surfaces of controlled structure there applied is layer of electroactive material and layer of electrically conductive material, wherein the electroactive material used is materials from organic and inorganic substances capable of changing their resistance depending on the change in the crystal structure of the metal sample, from each local section of the electrically conductive layer coinciding with the controlled section of the structure, bends are made in the form of conductors, the second ends of the conductors are used for connection of the measuring input of the measuring instrument, wherein presence of defects of local sections of structures is established by deviation of measured value of resistance of local area from reference value of resistance of this section, wherein reference values of resistances of local sections are pre-measured for initial good condition of the controlled structure.

EFFECT: technical result is possibility of increasing sensitivity and simplifying non-destructive inspection methods.
