Research Interests: numerical modeling of material failure using discrete approaches such as peridynamics and the discrete element method, multiscale simulation of damage processes and fracture mechanisms, development of computational strategies for the analysis and interpretation of acoustic emission signals, structural health monitoring and failure prediction based on acoustic emission, integration of experimental and numerical methods for the assessment of damage evolution in materials and structures
Acoustic Emission (AE) monitoring provides a window into the rapid energy release accompanying damage processes in structural materials. The field has evolved from qualitative diagnostics to quantitative, physics-based interpretation, yet progress is often hindered by the gap between microstructural mechanisms and the measured AE signals. Discrete numerical methods offer a natural framework to model fracture, crack interactions, and progressive damage at meso- and micro-scales, and to relate simulated events to observed AE waveforms. By linking discrete processes to recorded signals, these approaches enhance predictive capability, improve nondestructive evaluation, and support safer design across engineering applications.
This Special Issue, under the title Discrete Numerical Methods for Modeling and Interpretation of Acoustic Emission, aims to advance the role of discrete numerical approaches in both modeling mechanical systems and interpreting AE data. It seeks to foster methodological developments, experimental–numerical integration, and cross-disciplinary applications that bridge theory and practice. Submissions from computational mechanics, materials science, structural health monitoring, and geomechanics are encouraged to advance the state of the art.
