{"cited_by_count":1140085,"description":"This cluster of papers focuses on the application of guided wave structural health monitoring techniques, particularly using piezoelectric sensors and ultrasonic arrays, for damage detection and assessment in composite structures. The research covers topics such as guided Lamb waves, impedance-based health monitoring, nonlinear ultrasonic techniques, wave propagation in materials, and non-destructive testing methods.","display_name":"Ultrasonics and Acoustic Wave
