Domain methods of modeling ultrasonic wave propagation give a full displacement field solution which can be useful in studying physical phenomena associated with the nondestructive inspection of materials. A number of applications have been studied which make use of this attribute including the analysis of oblique echoes in thick composites, the simulation of SAFT reconstructions, the validation...
One particularly important factor in ultrasonic NDT studies is the detailed knowledge of the ultrasonic energy interaction with the material under test. Since the finite element method (FEM) can be used to solve the hyperbolic partial differential equations, which govern ultrasonic wave propagation, FEM solutions can be used to mimic a SAFT measurement. The goal of this project is then to use the...
