Elastic modeling of ultrasonic wave propagation for NDE
conference paper
A 2D finite difference scheme has been implemented on a mini super computer
for the simulation of elastic wave propagation in NDE and seismic exploration.
For homogeneous media, this explicit second order scheme was found to be
accurate to within 5% to 10% for grid sizes of 1/10 wavelength and Poisson
ratios below 0.4. Examples representing crack detection below a cladded
surface and the inspection of thin surface layers demonstrated a good
qualitative agreement between numerical and experimental results.
