Originální abstrakt

Acoustic emissions in materials might be generated by several different physical processes. Distinction of these processes can be supported by analysis of the recorded signals. An AE signal itself is not directly related to its origin. Signals are affected by many factors such as the tested specimen, waveguide transfer function given by structure and homogeneity of material, transfer function of used sensors, etc. This work aims to identify signal features that are correlated with acoustic emission source type by analyzing artificial acoustic emission events. Signals are generated using a piezoelectric transducer and a signal generator that emits signals with various parameters.
