Abstract
An acoustic emissions testing device includes a testing sample, an acoustic sensor communicably coupled to the testing sample, and a load that is exerted on the sample. The acoustic sensor detects one or more acoustic events occurring within the sample. The acoustic sensor transmits data to a data recorder, which includes a processor and storage medium for executing instructions provided by a software residing within the storage medium. Upon executing the instructions on the transmitted data, the toughness of the sample is objectively determined and can be ranked comparatively to the toughness of other samples. The instructions provide for categorizing the data into possible acoustic event points and background data points, interpolating a background noise curve, determining the actual acoustic event points, and calculating the area under each actual acoustic event point.
