Signal Analysis for High Speed Acoustic Data Using Acoustic Emission Analysis Tool
Abstract: Acoustic Emission (AE) refers to the generation of transient elastic waves produced by a sudden redistribution of stress in a material. In this work, AE analysis tool is utilized to process high speed AE data. In the whole work, simplification of raw data detected using different AE sensors and then filtering of the data is done with the help of AE Analyzing tool and after that different signal analyzing functions/algorithms (FFT, STFT and its spectrogram) on MATLAB is applied. The AE has analytical functions like Total, Maximum, Minimum and Average. The millions of the data point corresponding to micro-second scale of AE data are simplified into thousands or hundreds of data points (by opting second-wise, minute-wise or hourly data) by using this AE tool and thereafter it can be analysed efficiently and speedily.
Keywords: Acoustic Emission AE, Fast Fourier Transform FFT, Short time Fourier Transform STFT, Universal Testing Machine UTM
