Applied Sciences Webinar | Advances in Acoustic Emission Technique: Test Interpretation and Numerical Simulations, 13 April 2023

Acoustic emission (AE) is a known technique for obtaining information about the critical conditions of structural systems. This system could be a tectonic plate with a characteristic length of km or an electronic device with a length of millimeters. The excitation that produces the acoustic emission events can be induced by different sources, including forces or other mechanical excitation. Several global parameters can be computed using AE data, and it is known that the evolution of these parameters in particular circumstances defines when and how the structural damage process evolves to collapse. Generally, it is not possible to prove a bidirectional, unique link between the AE signals and the damage process. For this reason, the numerical simulation of these kinds of mechanisms could furnish useful information to aid in the interpretation of AE experimental tests. Several strategies can be used, from the classical finite element model approaches to discrete element procedures, such as peridynamics, or other similar strategies where the possibilities of simulating spontaneous fractures can be more naturally harnessed. We posit that achieving such results could be a useful contribution to the scientific community. Therefore, the aim of this webinar is to bring together researchers working in the field of AE and numerical simulation, both at the material and structure scale. With it, we expect to provide novel insights on the application of this synergic approach to a wide variety of materials (concrete, steel, masonry, composites, etc.) in the field of physics, the mechanics of materials, and civil engineering.
