Description

To ensure safe operation, nuclear power plants must be inspected periodically. One of the most commonly used nondestructive inspection methods uses ultrasound to detect internal flaws. However, the complex structure of some joints between different components greatly complicates the ultrasonic inspection. These joints, which consist of welds with varying and sometimes anisotropic elastic properties, can distort the ultrasonic beam and produce unreliable results. To understand the propagation of elastic waves through such materials, beam models are used.

Ultrasonic beam propagation through a bimetallic weld — a comparison for predictions of the gauss-hermite beam model and finite element method
