This paper presents a combined finite element simulation and experimental analysis of damage-induced acoustic emission (AE) in advanced sandwich composite structures (ASCS). Towards this, finite element analysis of AE-wave propagation in a honeycomb-core ASCS with AE-sensor network is carried out in ABAQUS. The numerical simulation results are then successfully verified with laboratory experiments. Finally, the most probable damage source locations are effectively identified using the registered AE signals. A thorough assessment of different damage-source locations was carried out to evaluate the performance of the proposed online AE-source monitoring technique. The results distinctly represent the effectiveness of the proposed online monitoring framework for detecting damage growth/initiation induced AE-source locations in such multi-layered complex structures. Moreover, the proposed framework does not depend upon the operator’s expertise.
