Ultrasonic modelling of tilted surface-breaking cracks

Last updated on 02 September 2014 3:44

Many rail breaks are caused by rail defects. Many cracks initially run at about 20°/160° to the surface of the rail and so do many masking cracks. The cracks are routinely detected and sized using piezo-electric trasducers. These generate compressional, shear and Rayleigh waves. Predicting amplitudes of echoes from surface-breaking...
