Abstract

During static structural qualification tests, it is always preferable to monitor in real time the health of the structure in a non destructive manner. In the event of any premature failure occurring during loading, it is preferred that this is detected immediately at an early stage to prevent the catastrophic failures in service at a later stage. Acoustic Emission (AE) is the only proven technique that is presently available for the detection and to monitor the growth of defect in real time. Acoustic Emission (AE) technique can provide in-situ information of such behavior as mentioned above. It is not sufficient to obtain the information about the damage initiation and source location. It is necessary to obtain more information about the nature of failure in the composite structure as the failure modes in composites are more complex. This research work is carried out to identify the signatures of failure modes.
