Paper Abstract
In NDT (nondestructive testing) often a side-drilled hole (circular cavity) is used for calibration. In this paper scattering
of ultrasonic waves by a circular hole is studied. The ultrasonic wave is generated by a transducer of finite dimension. A
newly developed semi-analytical technique called Distributed point source method (DPSM) has been adopted to solve
this problem. Even though this is an old problem the complete field of the scattered waves in presence of a hole in a half
space near its boundary has not been shown in the literature yet. The scattered ultrasonic field (stress and displacement)
is computed using DPSM and presented in the paper. Solution of this problem will also help us to understand the
distortion of the ultrasonic field in the half-space due to the presence of a circular anomaly (cavity or inclusion) which
plays an important role in structural health monitoring.
