Metal structural plates are extensively used in various engineering structures due to their high strength, high-temperature resistance, toughness, and plasticity. However, they are susceptible to damage from external loads and impacts over time. The

Traditional methods for detecting damage in engineering structures often use offline static damage detection. To enable the real-time and precise identification of dynamic damage while maintaining symmetry in engineering structures, this study primar

This study presents a novel area-scan damage identification method based on Lamb waves which can be used as a complementary method for point-scan nondestructive techniques. The proposed technique is able to identify the most probable locations of dam

Flexible sensors play an increasingly important role in damage detection of curved sheet-like structures in large-scale equipment. The sensor array is widely used in plate-like structures because it can collect damage information in a centralized man

This paper presents a procedure for damage identification and characterization on plates, based on the principal curvatures of their first mode shape. Each mode shape represents the displacement of the structure at its corresponding natural frequency

This paper presents a procedure to identify damages in beam structures using a damage index defined based on the first mode shape of the structure. The proposed damage index is sensitive to the geometrical parameters and material properties of the st

Lamb waves and electro-mechanical impedance based damage detection using a mobile PZT transducer set

Ultrasonics. 92:13-20
Lamb waves and electro-mechanical impedance (EMI) based methods are increasingly used in damage detection owing to their high sensitivity to small structural defects. Lamb wave based methods are effective in detecting damages in a large area and elec

This study presents a Probability based Impact Localization (PIL) method for plate structures. To this aim, an Error Index (EI) is introduced based on the Time of Arrivals (TOAs) of impact induced flexural waves. Due to dispersive characteristic of f

Lamb wave is widely recognized as one of the most encouraging tools for structural health monitoring (SHM) systems. In spite of many favourable characteristics of Lamb wave for SHM, real-world application of these systems is still quite limited. Besi
