| Popis: | The article deals with the use of acoustic emission to identify the formation of cracks during the mechanical loading in the corrosive attacked weldment S235JR+N. The experiment includes the methodology for continual record of emissive signals, data analysis and monitoring of material response to monitor mechanical stress effect in real time. There is possibility to observe response of corrosive degraded samples in real time during mechanical stress through the suitably designed methodology of detection, process and analysing of acoustic emission signals. It is possible to gain new information about processes rising inside the material by this way of data measurement. The signals of acoustic emission can be used as the way of identification for the micro cracks rising in the inner and also external structure of effortful materials. |
