R. Romanyshyn, V. V. Koshovy, I. M. Romanyshyn & R. V. Sharamaga
A new aproach to the estimation of degradation of material in the bulk of product based on backscattered ultrasonic tomography is presented in the paper. The proposed approach is based on the physical assumption that material degradation leads to the increase of structure heterogeneities of material and increase of the variation of physicomechanical properties of material. That’s why the estimation of degradation degree consists in the estimation of the chaoticy of scattering property tomographical images....
