By correlating a change of load with a change in acoustic emission counts, there exists a possibility that an alternate method of incipient failure detection can be predicted. This presentation is made in the form of a literature review and a first hand experimental investigation. Fifteen specimens were procured and tested. Load was recorded by the Instron Tensile Test Machine and the acoustic emissions were recorded on tape. A linear regression analysis was then performed on the data collected. The conclusions drawn from the research indicate that the correlation of load versus acoustic emissions indeed exists. Also, a good indication of incipient failure prediction is the engineering yield point.
