This paper reports our experiment on training a three layer forwards n
eural network with backpropagation algorithm (BP) to memorize acoustic
emission (AE) behaviors of magnesium ahoy during fatigue test process
and perform the mapping from Ae behaviors to fatigue crack propagatio
n. This study reveals the potential possibility of using artificial ne
ural networks for automated AE testing. Simulation results are very en
couraging and conclusively in favor of this attempt.
