Descrição: The paper reports on a molecular dynamics study of acoustic emission in an indented iron crystal for analyzing the effect of dislocations on its signal. The acoustic response of the system to loading is evaluated as forces acting on sensors which represent separate atomic areas located on the specimen surface. The analysis of acoustic emission and internal specimen structure shows a significant change in the emission signal due to the emergence of dislocations on the specimen surface.
