Abstract

The article deals with the possibility of estimating the distribution of electrical properties along the depth of the object using eddy current method of nondestructive testing. Experimental testing of stress-strain state estimation of titanium alloy plate at bending by means of transducer signal acquisition in a wide range of frequencies is carried out. The experimental data was analyzed using analytical calculation of the transducer signal. As a result of the studies, the relationship between mechanical stresses and electrical conductivity was established, and the possibility of effective control of the stress level by eddy current method was shown.
