Description

Initiation and propagation of surface breaking cracks is a major factor limiting life of many engineering structures [1]. A significant effort has been expended towards developing non-destructive methods to detect and size surface breaking cracks [2]–[5]. Due to their high sensitivity ultrasonic and eddy current methods are the two most widely used in practical inspections. For example, surface acoustic wave is capable of detecting a 50¼m deep semicircular crack [4, 5]. About the same size cracks can be detected by eddy current method in a number of conducting materials.
