However, most of the present systems scans and evaluates the small part of these information only. The reliable determination of the AE source parameters (position, range, type etc.) meanwhile isn't satisfactory solved. The superior grant purpose is to elaborate the methodology of the emission source characterization, to be able identify the signal source by the scanned signal. To solve this inverse elastodynamics problem is needed to know the Green functions of the test solids and sensors. Especially, the numerical determination of these functions is purpose of the submitted project. To this purpose will be tested FEM computing system by using the solved analytical exercises in the past. The characteristics of the numerical model with reference to accuracy and reliability of the results will be set. The response of the broad"@en . . . . . .
