| Abstract |
| | Two techniques developed to aid in inspection of rails, axles and welded fabrications are described. These techniques enable ultrasound to be visualized in transparent liquids and solids in a manner that is shown to be relevant to engineering needs. The first of these techniques relies upon Schlieren optics that uses a Z-configuration mirror system. It is applied in wheel probes used in ultrasonic rail testing vehicles. The second visualization system relies upon photoelasticity to study wave propagation in glass models. The interaction of ultrasound with defects is briefly discussed, concentrating in particular on the inclined kidney-shaped defect that can be found in the head of a rail. 12 ref.-AA |
