description |
The acoustic emission technique is used for monitoring the fatigue failure
mechanisms in reinforced concrete beam under three point bending. The
analysis was conducted by using the bathtub curve method plotted from
acoustic emission data. In this study, the fatigue behavior was divided into
three stages. The first stage is involved with the decreasing failure rate,
known as early life failure or burn-in phase, the second stage is
characterized by constant failure rate and the third stage is called the burnout
phase which is an increase of failure rate. The three parameters used in
analyzing is the fatigue behavior for each stage of failure which are severity,
signal strength and the cumulative signal strength. From severity analysis,
the range of each stage of failure had been determined while from signal
strength analysis, the initiation of distribution of crack had been detected
through the fluctuation of signal strength. Cumulative signal strength
parameter provides a clearer view of the initiation and distribution of crack. |
