Description

Both finite difference and finite element techniques have been shown to be capable of modeling the propagation of acoustic emissions (AE) [1,2]. However, those calculations could also be done using the simpler Green’s function methods [3]. In this work the finite element method is used to model a problem that includes complexities that cannot be handled using the Green’s function methods.
