title = "Identification of acoustic emission sources using in situ microscopy",
abstract = "A novel technique combining mechanical testing inside a Scanning Electron Microscope (SEM) in conjunction with Acoustic Emission (AE) monitoring is proposed to identify the primary AE signals due to plasticity and fracture of metallic specimens. The coupling between quasi real-time microscopy with actual in situ nondestructive evaluation falls into the Integrated Computational Materials Engineering (ICME) framework and the idea of quantitative data-driven characterization of material behavior. The focus on this article is to cross-validate damage incubation and initiation with the use of AE monitoring inside the SEM chamber. To this aim, Aluminum 2024-T3 sharp notch specimens were tested both inside and outside the microscope. Load data were correlated with both AE information and microscopic observations of microcracks around grain boundaries as well as secondary cracks, voids, and slip bands. The preliminary results are in excellent agreement with similar findings at the meso-/macroscale. Extensions on the application of this novel technique are discussed.",
