Paper Abstract

Acoustic emission is a widely used and efficient method for structural damage monitoring. Analytical modeling of wave propagation due to dislocations by considering the source as a self-equilibrating moment tensor is a commonly used approach is seismology. In this paper the acoustic emission source definition using moment tensor approach is studied and tried to implement it in thin plates with micro crack acoustic emission source. Depending upon the characteristic of micro crack formed the moment tensor excitation also changes. A study has done to identify the moment tensor components for mod 1, mode 2 or mode 3 like fracture micro crack formation from the classical definition of moment tensor.
