Abstract The magnetomechanical effect describes a phenomenon for magnetic materials, and most studies focus on ferromagnetic materials. To further study the mechanism of the magnetomechanical effect, the characteristics of the magnetomechanical effect of aluminum alloy 2A12 are experimental studied in this paper. The experimental magnetic hysteresis losses of the aluminum alloy under different stresses and plastic deformations are calculated, and its quantitative correlations with stress and plastic deformation are compared. It is found that (1) in the elastic deformation stage, the magnetic hysteresis loss increases approximately linearly with the increase of stress; (2) in the plastic deformation stage, the magnetic hysteresis loss decreases approximately linearly with the increase of plastic deformation. This study not only has engineering application value to quantitative evaluation stress and plastic deformation of aluminum alloy 2A12 but also has significance and reference value to further study the mechanism of the magnetomechanical effect.

1 Introduction Failure affects the structural safety and service life of structural/engineering material applications. To avoid the huge loss caused by the structural failure and ensure the security and development of human society, it is very important to detect and evaluate the structural damage before the failure of the structure. Mechanical stress is the leading factors of structural failure during the design, manufacture, and in-service process of structure. Therefore, the detection and evaluation * Hongmei Li [email protected] * Chuntian Zhao [email protected] 1

of stress or plastic deformation before structural failure are very important to ensure the safety and estimate the life of the structure [1, 2]. Because the magnetic properties of many materials have correlations with stress, plastic deformation, and structural defect and the testing of magnetic field is simple and convenient for application, the detection and evaluation of stress, plastic deformation, and structural defect using magnetic method attract increasing attention of scholars [3–8]. A physical phenomenon that mechanical stress changes the magnetic properties of ferromagnetic materi
