Effects of stress on magnetic and eddy current inspection techniques. Magnetic monitoring of stress-induced changes in pipelines. Measurement and analysis of reversible and irreversible effects. High resolution MBN measurements of magnetic uniformity and surface defects. Other Neutron diffraction measurements of stress concentrations near defects.
All experiments use computer control and data logging.
2 Rotary dynamic test rigs for leakage flux detectors. Numerous static test rigs. 4 test rigs for magnetic monitoring of bending stress changes. 2 Test rigs for examining the effects of line pressure stress on MFL signals. The majority of graduates from Prof. Atherton's AMG are employed in industry.
