Reference-free damage detection using instantaneous baseline measurements
TL;DR: A novel method of guided wave-based structural health monitoring is developed in which no direct baseline data are required to identify structural damage and this new method accomplishes reference-free damage detection by acquiring what is referred to as an instantaneous baseline measurement for analysis.

Damage Studies in Composite Structures for Structural Health Monitoring using Strain Sensors
TL;DR: In this paper, the effect of skin-stiffener separation on the strain profiles of composite testboxes was investigated using both strain gages and fiber Bragg grating sensors, and different types of testboxes were fabricated and tested to compare bolted, co-bonded and co-cured configurations.

Mathias Kersemans,Arvid Martens,Koen Van Den Abeele,Joris Degrieck,Filip Zastavnik,Lincy Pyl,Hugo Sol,Wim Van Paepegem +7 more
TL;DR: In this paper, the hybrid compliance-stiffness matrix method for simulating wave propagation in (delaminated) multilayered media with viscoelastic anisotropy has been confronted with high-quality amplitude and phase experiments on delaminated composites, obtained using the ultrasonic polar scan setup (UPS) in transmission by considering harmonic and pulsed ultrasound.

Reference-Free Damage Identification in Plate-Like Structures Using Lamb-Wave Propagation with Embedded Piezoelectric Sensors
TL;DR: In this article, an instantaneous baseline damage detection based on cross-correlation (CC) analysis is carried out to detect the damage, and the influence of artificial crack (cut-damage) on propagated Lamb waves is investigated.

Dissolvable thermoplastic interleaves for carbon nanotube localization in carbon/epoxy laminates with integrated damage sensing capabilities
TL;DR: In this article, a hierarchical composite with localized toughening and integrated damage sensing capabilities is described, which is based on a nano-engineered hierarchical composite, which consists of thermoplastic phenoxy interleaves which dissolve in epoxy resin upon heat.

Ultrasonic Waves in Solid Media
TL;DR: In this article, the theory of elasticity was introduced and basic formulas and concepts in complex variables in the theory and application of wave propagation were discussed. But the authors did not consider the effects of wave scattering on the wave propagation experiments.

The impact resistance of composite materials — a review
TL;DR: In this article, the impact response of continuous fiber-reinforced composites is reviewed and an attempt is made to draw together much of the work published in the literature and to identify the fundamental parameters determining the impact resistance of continuous fibre reinforced composite materials.

Comparison of the low and high velocity impact response of cfrp
Wesley J. Cantwell,John Morton +1 more
TL;DR: A series of low and high velocity impact tests have been conducted on a wide range of cfrp laminates to examine the initiation and development of damage under these two widely differing loading conditions as mentioned in this paper.
