Outline of Final Research Achievements |
We developed a high-performance Magneto-Acoustic Emission measurement system for biaxial plane stress evaluation. We measured the MAE of Nickel and SM490A under three plane stress state, i.e., 1. uniaxial compression, 2. equibiaxial compression and 3. biaxial compression (principal stress ratio is 1:2). It is found that the the dependence of MAE characteristics on the applied magnetic field and stress directions differs according to each plane stress state. In the result, it is shown that the 2 dimensional stress evaluation is possible by measuring MAE with changing the applied magnetic field directions.
