Introduction and Topics:

Composite structures are essential in high-performance engineering due to their exceptional strength-to-weight ratios. However, the inherent complexity of failure mechanisms—such as delamination, matrix cracking, and debonding—necessitates sensing and monitoring solutions beyond traditional techniques. This special session focuses on recent breakthroughs in sensing technologies and integrated monitoring frameworks designed specifically for composites.

Emphasis is placed on the transition from passive observation to high-fidelity damage assessment and quantification. The scope covers innovative self-sensing methods and advanced diagnostics using ultrasonic waves, acoustic emission, and other high-resolution tools to characterize structural integrity. By highlighting the synergy between novel sensing technologies and advanced signal characterization, this session aims to present progress in detecting early-stage damage of composite structures.

Topics of interest include, but are not limited to:

• Self-sensing and Smart Materials: Piezoresistive effects, conductive composites, and multifunctional composites for intrinsic sensing.
• Advanced Ultrasonic and Wave-based Monitoring: Ultrasonic guided waves, phased arrays, and non-contact laser ultrasonics for damage imaging.
• Innovative Embedded and Surface Sensing: Fiber optics, piezoelectric wafer active sensors, and flexible electronic patches.
• Acoustic Emission and Passive Monitoring: Signal processing for damage evolution tracking and failure mode classification.
• Industrial Applications: Case studies and practical implementation of damage monitoring in various composite structures.
