| Abstract |
| | Various aspects of the evolution of the magnetoacoustic measurement technique from a laboratory procedure into an established component evaluation tool have been previously reported. Efforts to apply the magnetoacoustic measurement technique to determine residual stress states in railroad wheels have been hampered by dealing with complex geometries and ill-defined stress gradients. The use of finite element magnetic field modeling has recently been employed to assist in the analysis of test data. Specifically, through the use of such modeling, the electromagnet configuration used in testing has been shown to provide effective bulk magnetization of the wheel rim, albeit in a non-uniform distribution. This result is discussed with a particular emphasis on the implications for railroad wheel stress determination in randomly selected wheels. |
