Subject Evaluation
Nondestructive Evaluation, NDE, Residual Stress Measurement

Two devices designed to non-destructively determine the residual stress state of railroad wheels were evaluated. The first device was a magnetoacoustic design developed by the National Aeronautics and Space Administration, Langley Research Center in conjunction with the Association of American Railroads, Chicago Technical Center. The second device was an acoustic birefringence device developed by the National Institute of Standards and Technology. The evaluation involved comparison of results from the non-destructive devices with results from more conventional destructive analysis.
