Language eng - English Country CZ - Czech Republic Keywords acoustic emission source ; wave propagation ; FEM Subject RIV BI - Acoustics R&D Projects GA101/09/1630 GA ČR - Czech Science Foundation (CSF) CEZ AV0Z20760514 - UT-L (2005-2011) Annotation The paper deals with the acoustic emission source modeling by means of FEM system COMSOL Multiphysics. The following types of sources are used: the spatially concentrated force and the double forces (dipole). The pulse excitation is studied in both cases. As a material is used steel. The computed displacements are compared with the exact analytical solution of point sources under consideration.
