Abstract A new technique has been developed for acoustic-emission fatigue monitoring which facilitates the interpretation of dynamic micromechanical failure processes in materials, through the use of a new method for data presentation. In contrast to conventional acoustic-emission fatigue records in which the emission rate is plotted as a function of the number of fatigue cycles, the new technique produces a graph in which each acoustic event is plotted within a coordinate system of load vs. number of cycles. This approach results in the simultaneous recording of the relationship between sample load, acoustic-emission rate and number of fatigue cycles. Monitoring of 300M steel has established that it is possible to distinguish between fatigue-crack propagation, fatigue-crack closure and testing-machine noise using a single transducer.
