Since the parameters of the domain based magnetization model are extremely sensitive to the various physical conditions such as temperature, mechanical stress and so on, this paper tries to evaluates the stress effect to the magnetization characteristics of ferromagnetic materials in order to apply the nondestructivereliability diagnosis of the metallic structures.A key idea of this paper is based on the following facts that the parameters identification of a domain based magnetization model has been successfully carried out by a harmonic balance approach.As a result, it is found that the stress effect to one of the parameters expressing hysteretic property has been clearly deflected its values depending on the externally applied stresses.
