147505 - Role of Numerical Simulation in Future Ultrasound-Based Digital Twinning 

Abstract: 

The evolution and application of numerical simulations have become pivotal in enhancing the diagnosis, monitoring, and overall health of smart structures through ultrasound-based techniques. This presentation delves into the integration of numerical simulations with ultrasound diagnostics to predict, assess, and ensure the structural integrity and functionality of smart infrastructures. By exploring various numerical simulation techniques, particularly the Spectral Element Method (SEM), we highlight their critical role in addressing complex geometries, diverse material properties, and different damage types in smart structures. The applications of these simulations span across early development phases to sophisticated current implementations, focusing on non-destructive evaluation (NDE), structural health monitoring (SHM), and material characterization. Despite the substantial advancements in ultrasound-based diagnostics and the promise of digital twinning for future infrastructure maintenance, significant challenges persist. These include computational demands, modeling complexity, and the necessity for accurate material properties and boundary conditions. The presentation concludes with an overview of the current limitations of ultrasonic simulation techniques and proposes future directions to enhance the efficacy and applicability of numerical simulations in the realm of digital twinning. This advancement is anticipated to revolutionize the maintenance and evaluation of smart structures, pushing the boundaries of current engineering practices and paving the way for innovative construction and maintenance methodologies.
