Understanding Acoustic Emission Testing- Reading 1 Part B-A

Unfortunately, the routine use of
acoustic emissions as an
estimator of strength seems to be
an unlikely prospect, in large part
because of the scatter in the data,
as has been noted by Fertis. As an
example of the scatter in data.
Figure 16.6 indicates the variability
in the strength vs. total acoustic
emission counts relationship; the
within-batch variability is even
more severe, as shown in Figure
