Abstract

This paper describes the development of a forward modeling framework, QAE-Forward, of the complete acoustic emission (AE) process in real structures. Finite element modeling results are presented showing the modal pattern of radiated guided wave energy from a growing fatigue crack. This data will ultimately be used as an input to QAE-Forward. The challenges of obtained the same data experimentally are also demonstrated.
