Моделювання процесу вихрострумового контролю циліндричних виробів із неперервним розподілом електрофізичних параметрів

Abstract

The paper presents an approach to modeling eddy current testing of cylindrical products with a continuous distribution profile of electrical conductivity and magnetic permeability along the radius. The distribution functions of the electrical conductivity and magnetic permeability of the object, which can be used in modeling, are described. The convenience of the approach in setting input data for numerical calculations of the analytical solution of the direct problem when solving the inverse problem of restoring the electro physical parameters of the testing object is given
