| Summary: | The crack behaviour of brittle
engineering
material such as ceramic tiles is
deeply related to m
icro cracking propagation and brittle fracture
that occur
in
microstructure
.
In the present study,
the Acoustic Emission method is
applied
to
obtain
certai
n
information
required
from the crack activities
in the stress condition of
ceramic tile
.
Some
of the crack parameter
such as acoustic emission (dB), amplitude
(mV) and
signal energy
(ergs) can be measured by the analysis of acoustic emission
signal that g
ener
ated.
Moreover, t
he number of
micro crack event can be identified
by the ring down counting technique.
The
arithmetic average calculation from 25
samples of ceramic tiles with varies of load speed have been conducted to
achieve
more accurate results
.
T
hroughout the project, t
he correlation between the acoustic
emi
ssion and crack behaviour was
obtained by considering the microstructure
features
that existed
in the ceramic tiles. |
